Electric Power Quality Issues: Causes and Consequences

Published

power quality issues

Most of us think of power in terms of whether it’s on or off. But what many of us may not have given much thought to s the quality of that power. We need more than the naked eye to determine whether the power flowing to equipment is of good or poor quality.

Electric power quality issues can be very costly — in many different ways — for commercial and industrial facilities. Here’s more about what causes these problems and what can happen if businesses fail to correct them before consequences occur.

Four Types of Power Quality Problems

Facilities may experience four general types of power quality problems:

  • Harmonics: High-frequency current and voltage can stress the electrical distribution network, cause nuisance tripping and transformer overload. The eventual result can be premature equipment failure. Possible causes include; saturation at the magnetic core of electric motors or transformers, compact fluorescent lamps, LED lighting and older Uninterruptible Power Supplies (UPS).
  • Power factor: This ratio measures real power over apparent power to gauge how well a facility is using its power. Ideally companies should aim for a power factor higher than 90 percent. Utility bills tend to rise when it falls below this threshold. Transformers and certain kinds of high-intensity lighting can cause power factor imbalances.
  • Flicker: Flicker is a series of voltage fluctuations of varying magnitude and frequency. It’s caused by an event like a welder hitting an arc or the beginning of an induction load requiring a lot of power. Voltage can sag repeatedly over the course of seconds or even milliseconds. 
  • Over/Undervoltage: Voltage supply can be high or low depending on a few factors. A customer at the end of a distribution line might experience chronic undervoltage, especially if someone else on the line kicks off a large inductive load. Overvoltage can occur when a large load switches off within the facility. Electric motors starting up in a factor is one common cause of voltage sags.

As you can see, not all power ends up operating at ideal — or even safe — levels. Commercial and industrial facilities require specific corrective measures to offset these problems, like installing devices capable of industrial-level harmonic filtering. 

Consequences of Power Quality Problems

Perhaps the costliest consequence of power quality problems is premature equipment failure. After investing so much money into machinery and electrical devices, the last thing organizations want to see is the untimely malfunction of the very systems they need to function. Equipment failure can occur suddenly — like a blown fuse — or slowly — like gradual overheating leading to a shorter lifespan. It’s safe to say ongoing power quality issues can cost commercial and industrial concerns billions of dollars per year.

Of course, malfunctioning machinery can even go so far as to halt production and make “business as usual” impossible until it’s fixed. Another consequence is higher-than-necessary operating costs, especially when inefficient power factors are in the mix.

How to Identify Power Quality Problems

Given the potentially destructive nature of power quality problems over time, it stands to reason facility managers are trying to mitigate this problem as early as possible. Power quality meters are one way to get readings on what disturbances are happening, how frequently and to what degree. This empowers managers and engineers to isolate problems and rectify them as soon as possible.

The causes of power quality problems are myriad and the consequences are costly, which is why it’s important for organizations to take this threat seriously and find ways to mitigate them before too much damage occurs.

How to choose Whiskey?

Published

on

Whiskey is a strong alcoholic drink that is obtained from barley, corn, rye and wheat. To make this truly unique product, malting, distillation and aging in oak barrels are involved.

The average aging of whiskey distillery should not be less than three years, while the alcohol content in the drink is at the level of 40-50% (but there are some varieties with a strength of 60%). At the middle stage of production, it is possible to obtain a light shade drink, while it acquires a characteristic brown tone during infusion in oak barrels.

REGIONS FOR THE PRODUCTION OF WHISKEY

Scotland and Ireland are considered the birthplace of whiskey, while the production of the drink is actively developing in the USA, Canada and even Asian countries.

Whiskey can be divided into several groups, depending on the country of manufacture:

  • Irish is made from rye, barley and barley malt. This category of drinks has a mild, perfectly balanced taste, as well as a multi-faceted persistent aroma. Bright representatives of the Irish category – “Bushmills”, “Jameson”, “Finnegan”;
  • Scottish scotch tape distillery produced from barley malt and barley. Most scotch has a peaty aroma, as well as an unobtrusive smoky flavor. Bright representatives of Scotch whiskey – “Macallan”, “Chivas Regal”, “Hankey Bannister”;
  • American whiskey is produced from rye, corn and wheat. The composition of the drink is approximately 51% of corn alcohol. This product is often characterized by a sweetish flavor, while the most popular representative in this category is considered to be “Jim Beam”. The legendary “Jack Daniel’s” also refers to the American direction, since it is 80% composed of corn-spirit, but it is called as “Tennessee Whiskey”;
  • Canadian is an interesting drink made from rye. Such a product is labeled “rye” on the label;
  • Japanese is an original gourmet solution that resembles classic scotch tape in taste, color, and texture. A prominent representative of this category is Nikka, which is sold both on the Asian market.

The main varieties of whiskey

Based on what product is taken as the basis for the manufacture of the drink, it can be divided into four categories:

  • Grain, when cereals are used as a base;
  • Malt, when the drink is made from pure barley;
  • Blended, that is, a mixture of grain and malt;
  • Bourbon is an American whiskey that is made from corn grains, but it has some differences in production technology.

Malt whiskey is considered the “Gold Standard”, and it, in turn, is divided into several groups:

1.    “Single Malt” – a classic and one of the most common options, which is made from malted barley. Most often, the drink is based on a blend of alcohols of different aging periods, mixed from different barrels;

2.    “Single Cask Malt” – is made on the basis of alcohol from one oak barrel. It has a persistent taste and aroma, but at the same time it is less widely sold than the previous species;

3.    “Pure Malt” – the purest mix of single malt whiskey, which is combined into a single blend. A striking representative of this category is the iconic Ballantine’s.

The whiskey of the Blended variety, that is, a mixture of malt and grain varieties, stands out clearly. This is one of the most popular species, which occupies a large part of the market worldwide. Elite varieties of blended whiskey incorporate a large percentage of malt alcohol.

It is important! If the whiskey is blended, this does not mean that it is of poor quality. For example, top brands of whiskey, known throughout the world (Chivas Regal, Johnny Walker, White Horse) are also blended.

Exposure plays a role

The age of whiskey is determined by the maturity of the youngest alcohol in the blend. For example, if the label “Chivas Regal” indicates 18 years, then the youngest alcohol in the blend was in the barrel for at least eighteen years. The time after a drink has been bottled is not taken into account.

Important facts about exposure:

  • whiskey is aged in oak barrels from 3 years;
  • the exception is bourbon, which has a minimum aging time of 2 years.
  • most manufacturers insist on drinks for 5-12 years to get a perfect drink according to their taste and aroma characteristics;
  • with young varieties it is necessary to be careful because a short aging time can negatively affect the quality of the product;
  • A drink aged 20 years or more is considered a collection item.

Taste, aroma, strength

The classic aroma is the so-called Scottish when in the bouquet notes of charcoal are felt. Irish whiskey also has pronounced peat notes in the taste. The taste may vary, while at the beginning of the bouquet notes of wood, fruit and vanilla may be felt. Depending on the length of stay in barrels, the strength of different grades can be from 40 to 60 revolutions.

Irish technology for assessing taste, strength and aroma:

  • We evaluate the visual characteristics: color, overflow, transparency;
  • We study the aroma of a pure drink without diluting it with juice or cola;
  • Savor: take a sip and hold it in your mouth for several seconds, gradually swallowing the liquid;
  • Add ice or some water, try again.

Note! To assess the qualities of a drink, it is best to drink it in its pure form, use whiskey stones as a cooling element. And to determine your perfect whiskey, experts recommend trying several varieties at once. No wonder the Scottish wisdom says: there are no people who do not like whiskey; there are people who just have not decided on the grade to their liking.

If you want to dilute a strong drink, this can be done either with ice or with cold spring water. Why water? Because in whiskey, there are many different impurities with different densities, as well as the ability to dissolve in water in a special way.

As for the glasses, there is a Hollywood style of using this drink from a glass container with a thick bottom. Experts believe that it is in the curved “tulips” that the complex aroma is correctly concentrated.

Whiskey is perfect with hot dishes of beef, lamb, as well as smoked fish, warm salads, chocolate, berries.

Is it worth starting from the cost?

The high price does not guarantee that you will definitely like this expensive drink. The best option for a classic tasting is mid-range drinks: “Jameson”, “Jack Daniels”, “Ballantine’s”, not much more expensive than “Chivas Regal”.

If the task is to choose whiskey for a gift to the gourmet of this drink, you can give preference to collection options aged 20 years or more.

In all stores, the cost of whiskey is approximately the same, differing hardly by 15-20%. If you are offered an incredibly cheap option, the price of which is one third less than in retail outlets, then this is probably a fake. We wish you a pleasant tasting of the cult strong alcoholic drink!

CONCLUSION

But no matter how classic dem, it will not please you if the glass is half full of unsuitable whiskey. Let’s break up how to choose the right one, your whiskey.

Scotch, bourbon, rye whiskey, malt, blend. The world of whiskey is limitless, full of many classifications, styles and origins. All these features can be difficult to understand, especially for those who are just starting their acquaintance with this drink. Below you will find a lot of useful information necessary for choosing your first whiskey so that your first date with the “water of life” goes like clockwork and leaves behind a pleasant aftertaste.

There is no bad whiskey. Some whiskeys are just better than others.

Safety From Falls At Construction Sites A Complete Guide

Safety is a keystone of the construction industry!

Workers work from aerial lifts, scissor lifts, boom lifts, and are exposed to various hazards. That is why committing to safety for everyone, and the overall workplace is crucial.

One of the most popular causes of injuries and deaths on a construction site is falling.  42% of the construction workers’ injuries involve falls.

You might be unfamiliar with many details involved in working at heights, but one important consideration is worker safety. You need to identify- how falls happen, and what measures can be taken to increase safety at worksites! If you still don’t know where to start, here’s your complete guide to understand potential hazards and prevent falls:

What Causes Falls?

There are some common places where a worker can fall. This includes roofs, scaffolding, and ladders (specifically when they are misused), unprotected floor or roof openings.

There are also tripping hazards that result in falls, like exposed rebar and electrical cords.

Another reason is excessive noise at sites, which can make it hard for workers to listen to verbal warnings from their supervisors and co-workers.

Preventing Falls at Construction Sites

The first thing to preventing falls is a thorough inspection of a job site.

Inspections will help you identifying unprotected ledges, potential tripping hazards, and areas of excessive noise. Besides using safety devices and equipment, operator training is another crucial factor that promotes workplace safety.

Workers need to have AerialLiftCertification to stay up to date and create a safer workplace. It involves best practices and safety regulations on how to inspect heavy machinery and to use fall protection systems.

Here are some tips on how to prevent falls on a construction site:

Using Safety Nets

The safety nets system includes installing nets as close as possible to the work area. They protect employees working at heights by catching them before they fall. It provides passive protection means no need for inspecting certain personal protective wear. However, you must ensure that safety nets make sense in terms of safety. Some major points include:

  • Make sure you have enough clearance to prevent hitting the floor below the net. Do trials by dropping human-weight sandbags from a significant height to get assured.
  • Try to exceed the net to have maximum work area covered and secured.
  • Workspaces that are more than 25 feet above the floor need nets.
  • Nets must be installed in the areas that involve scaffolds, ladders, safety lines.

Install Guardrail Systems

Installing guardrails at the roofs and any area that is prone to hazards help prevent workers from falling. The top edge height of guardrails should be 42 inches above the walking surface.

In case if the wall is 20 inches high, install extra safety systems like mesh, mid-rails, screens, or solid panels. Guardrail systems are appropriate for ramps when working around hoist areas and holes.

Safety Harness

A full-body harness is a key component of a fall arrest system. It minimizes stress on a worker’s body by distributing the force of fall over a significant area of the body and keeps the employee in an upright position.

Make sure to wear the harness properly to ensure effectiveness and safety. It must have a snug fit, but still, provide the ease to perform tasks.

Lanyard or SRL

Length, hook design, material, and shock-absorbing functionality are some diverse traits of the connecting equipment. Two common connecting devices are SRLs and lanyards.

Lanyards are composed of cable that has a fixed length of 6 feet. They are designed with internal/external energy-absorbing functionality to use in fall arrest.

SRL (Self-retracting lanyard) also employs a cable lifeline that is available in varied lengths. The lifeline pulls out and retracts easily, much like a shoulder belt in a car.

Conclusion

Preventing falls has moved to the forefront, and the issues of injuries and equipment losses caused by falling from height are being addressed. With simple, easy to implement solutions, you can mitigate the hazards. Investigate the above options to find the right solution for you.

The 5 Best Things About Security Plastic Seals

Published

on

Plastic-Security-Seals

Security seals are mechanisms for sealing shipping containers to provide disability and some form of protection. These seals may aid in accidental or intentional detection of theft or contamination. Security seals are usually used to protect truck trailers, ship containers, chemical bottles, customs-free airline trolleys, and meters. They are usually considered an affordable way to provide manipulative evidence of intrusion into restricted places.

Best Things About Security Plastic Seals:

1- Used in Medical Emergencies:

Installation of protective seals in the field of medical emergency is often overlooked. Safety seals are not only suitable for first aid kits, but also for all emergency equipment, such as extinguishers, parachutes and other first-aid and rescue support kits, safety seals are a common requirement.

Both screens ensure perfect conditions and availability of the contents of the emergency equipment. Furthermore, they are designed to be easily breakable so that time is not lost in the extreme.

2- Used for Ballot Boxes in Elections:

The legitimacy of any democratic vote depends upon adequate assurances to prevent fraud and intervention in the electoral process. In this context, it is important to use security seals to seal boxes. This safety seal not only guarantees the origin of the boxes but also prevents attempts to alter the contents of the boxes. Polls can also be protected by means of security labels or void tags to prevent unauthorized opening.

3- Transport of Cash and Gold:

Cash in transit is regulated to avoid transportation fraud or traceability losses. This is why the financial sector and specialist transport firms will use safety seals to mark cash operations correctly.

Certain passive protection devices for the carrying of valuables are likewise bags (e.g. for the carriage of sensitive documents) and cash bags.

4- Transport of Hazardous Goods:

Artillery and ammunition transport is another not widely publicized use of safety seals. Nevertheless, the use of safety seals is mandatory, since the contents of containers and products and the packaging of weapons must be protected. In fact, artillery and ammunition movements are included in the transport of dangerous goods, requiring in comparison to all other transport types compliance with strict safety requirements.

5- Transport of Biohazardous Chemicals:

The transport of biological and laboratory samples is subject to strict regulations that always monitor their safety. Security seals are used to correctly identify and prevent tampering with the contents of each package or bag. An error of this kind could be deadly and lead to a biosecurity hazard.

Different Kinds of Security Plastic Seals:

These are the different kinds of plastic seals.

1- Cable Seals:Cable seals are new long-lasting seals used for valve sealing, new locked doors and other components with a tiny opening through which cable wire can be inserted. These cable seals comply with ISO 17712 safety requirements in order to be used in high-security situations such as international cargo transport. Different jobs in different sizes require cable lengths, but excess cable length can be easily adjusted. These are typically between 1.5 mm and 5 mm in different cable diameters.

2- Bolt Seals: Bolt seals are a very high-security screen alternative that has a complicated locking mechanism but is self-locking so that they do not require tools and are easy to set up. These have a steel bolt and an obvious part of the body that is manually attached to form a seal. These can be configured for additional security levels, by color, print and barcode. Such seals are suitable for containers, door locks, and cross-border shipping. Such heavy-duty seals require the removal of a bolt cutter.

3- Fixed-Length Plastic Seals:  include the best kind of plastic seal, with breaking strengths between 80 and 135 lbs. Such seals are particularly well suited for securing cargo for truck shipments. Fixed-length seals are inexpensive so when costs are a problem they are a good option.

4- Plastic Pull  Resistant seals: Pull-tight screws are similar to plastic sticks with a fixed length, except that they have a greater variety of break strengths and are adaptable for specific requirements. For instance, pull-resistant screens can be used to screen hazardous waste, extinguishers, cash bags, vehicle doors, and more. Adjustable plastic displays are a good choice if you have several flexible needs.

5- Wire Seals: Wire stitches also have multiple variants similar to pull-tight plastic stitches, but are less likely to break their metallic wires. These are suitable if the seals have to pass into small openings.

6- Seals with a Metal Collar: Steel strap seals with the exception of the material are identical to fixed-length plastic seals. Your material makes it longer-lasting than plastic brace seals. You may increase the safety level of metal strap seals with customized numeration, printing and bar codification. Metal strap seals, like the plastic alternative, are a good choice for trucking cargo.

7- Padlock Seals: Padlock seals are relatively small and very easy to use. These are commonly used to avoid opening doors. Wire padlock seals are ideal for the securing of meters and containers, while plastic padlock seals are ideal for securing carts for food, drink, and first-aid kits.

Top 10 Features of Egyptian Museum

Published

on

the Egyptian Museum

All of ancient Egyptian history is here, from the earliest Paranoiac artifact ever discovered to treasures from the era of Cleopatra, the last in a dynastic sequence of divine kings and queens stretching over three millennia. It is said that the museum displays more than 120,000 items, with at least that many again stored away out of sight in the basement. The real crowd-pleasers are the treasures from Tutankhamun’s tomb, but there are many hundreds of other precious antiquities here of at least equal significance and beauty.

1- The Museum Building

Egypt’s first national museum of antiquities opened in 1863. It was rehoused in the current pink, purpose-built premises in 1902, which were designed in Neo-Classical style by French architect Marcel Dourgnon.

2- Auguste Mariette

The Egyptologist Mariette, who discovered the Serapeum at Saqqara (see p40), was the founder of the first national museum of antiquities in Egypt. His sarcophagus rests in the garden in front of the Egyptian Museum.

3- Central Hall

The museum is on two floors. On the lower floor galleries are arranged in chronological order clockwise around a central hall dedicated to large statuary; this is also where you will find the Narmer Palette

4- Old Kingdom Galleries

Immediately to the left of the entrance hall, these galleries contain artefacts from the era of the Pyramid builders. Particularly beautiful are three slate triads each depicting Menkaure, builder of the smallest of the Giza pyramids, flanked by two goddesses

5- New Kingdom Galleries

This long gallery is devoted to the mightiest pharaohs, including Tuthmosis III, Amenhotep II and Ramses II, during whose rules Egypt expanded its borders south into what is now Sudan and north to the Euphrates

6- Amarna Room

Room 3 contains pieces from Amarna, the short-lived capital of the “heretic king” Akhenaten. His daughter, Princess Meritaten, is characterized by an elongated face and full lips.

7- Tutankhamun Galleries

Almost half of the upper floor is devoted to some of the vast numbers of items excavated from the tomb of Egypt’s famed boy-king (left), which range from everyday items such as gaming sets and footstools to the giant gilded shrines and sarcophagi that fit one inside the other like Russian dolls.

8- The Royal Mummies

The desiccated bodies of some of Egypt’s mightiest rulers are displayed in two rooms on the upper floor of the museum. Of the eleven royals present, the most famous are Seti I and his son Ramses II, whose colossi adorn a great many monuments in Upper Egypt.

9- Animal Mummies

The ancient Egyptians mummified animals as well as people. This room on the upper floor of the museum is full of animal mummies, from cats, mice, and fish to crocodiles, sacred to the god Sobek.

10- Ancient Egyptian Jewellery Rooms

These two rooms contain dazzling examples of royal jewelry from the New Kingdom period (left). Many of these items were discovered in 1939 at Tanis, an ancient site in the Delta region.
