Tips to Minimize the Buzzing Noise of Instrument Transformer Equipment

 Humming and buzzing sounds are commonly heard from transformers. The main cause behind the noise is magnetstriction. It is a process in which a magnetic steel sheet changes its dimensions or shape when magnetized. Again, when the magnetization is taken away it goes back to its original shape. The sound it generates might be controlled to some extent but cannot be completely removed. It is a vibrating sound that imitates the sound produced by generators and motors.

Here are some of the precautions that you can take while installing and mounting instrument transformer equipment, to reduce the humming noise.

 

Choose low traffic area for installation

If the transformer is installed in a high traffic area, the sound becomes annoying to people, especially if the surrounding noise is lower than the unit’s sound level. That is why it is advised to maintain at least one low traffic area between the transformer and high traffic spaces in commercial or residential buildings etc.

 

Corridors, corners, and stairwells should be avoided

The corridors, places near the ceiling are the places which increase noise and that is why installing a transformer in such places is certainly not a good idea. Similarly, the corners of a room also louden sound.

 

Install the transformer on a solid plane

Transformers should always be installed on heavy and dense surfaces like concrete walls or floors. Because plywood surfaces or thin curtain walls accelerate the humming sound making it intolerable. Mounting surfaces should be ten times heavier than the transformer itself.

 

Tighten the bolts enclosures

Make sure that the screws and bolts on the transformer’s cover and top have been tightened properly. Loose parts will vibrate when the transformer is working and this will automatically increase the noise.

 

Use oil barriers

Using oil barriers and cushion padding might help reduce the sound and control it from spreading. Though these are not capable to reduce the vibrating sound themselves but they reduce the frustration it causes among people staying in nearby areas.

 

Stick to a flexible installing method

Using additional dampeners along with flexible installing method and connection is highly recommended while installing these transformers on ceilings, walls, or frames. This will stop metal contact between the mounting surface and the transformer, to control sound transmission.

 

Apart from these above-mentioned techniques, you can always opt for the new and advanced technology, designs, materials, and installation method when you are planning to install a transformer. These days, stiffeners and other materials are used in transformer tanks to decrease the operating sound. So do not overlook the modern solution before finalizing the project.

Tips to Follow While Buying an Instrument Transformer Equipment in the USA

Many people believe that purchasing an Instrument transformer equipment is an easy task, but the fact is, a faulty product can cause several damages. Whenever we overlook those markings at the back of the box or ignore a slightly damaged product, we leave room for fatalities. Of course, everyone doesn’t have full knowledge of instrument transform requipment, so we are going to discuss some basic tips which can help you choose the right product.

 

Meets Statutory Safety Requirement

Before buying a transformer, it is important to match its legal safety requirements to the electricity regulations in the USA. This is especially true if you are buying any product outside the USA. Just match basic things, such as under what environmental conditions and power supply it is suitable to use this product.

 

Read the Guarantee Booklet

Electrical products generally have a specific span of warranty/guarantee period. If the manufacturer doesn’t offer the same, it is not suggested to buy the product, as it is an indication of low quality.

 

If the product comes along with a warranty/guarantee period, read the terms and conditions carefully to know under which conditions you can replace or return the product.

 

Follow Operation Manual Carefully

Every quality electrical product comes with an operation manual. Once you made the purchase, install it only after reading the manual thoroughly. You need to follow the exact procedure written in the manual. This is crucial to ensure that every safety measure has been taken while installing the product.

 

Check for Signs of Damage before Use

We can afford to ignore small signs of damage in décor items or furniture. But, any signs of damage, no matter how small, should not be overlooked in electrical products. So, it’s better to return or replace the product for safety purposes.

 

Prefer Energy Efficient Electrical Transformers

Energy-efficient transformers are sufficiently available in the market but rarely have a knowledge of these products. Energy-efficient transformers can highly decrease energy expenses, sometimes even up to 40%.

 

These types of transformers are known to reduce distribution loss and transmission. So, if you get an option to purchase an energy-efficient product, prefer to choose that.

As far as electrical products are concerned, avoid buying items that aren’t verified. It is not just about the quality but it is about compromising your safety as well.

Mistake to Avoid When Choosing Switchgear for Transmission and Distribution

 Buying on prime cost is the biggest problem. We see companies frequently purchase the lowest-priced option upfront, driven frequently by their rates commission or budget constraints. This often leads to problems in the long run such as higher maintenance, higher installation costs, and operations costs, and lower reliability. Utilities should scrutinize the entire ownership cost model to choose the best solutions for their applications.

Choosing switches not tested to ANSI/IEEE standards is another big mistake we often make. Many manufacturers test market responses to switchgear. These responses pass their own set of tests, and their marketing departments do a good job of persuading customers to accept low standard equipment. Industry standards are established to ensure the proper product applicability and operating staff’s safety. Many customers assume all manufacturers abide by the ANSI/IEEE standards. That’s not true. You should insist on it.

Major changes utilities will see in switchgear in the coming years?

•  Several big changes are coming. Switchgears that are not arc-resistant will be eliminated because liability for the engineers and manufacturers is too high. As companies become more aware of the risks associated with arc flash events and that all the major manufactures will provide arc-resistant switchgear, the regulatory bodies and market will make it mandatory to use safer products.

•  Requirements for automated switchgear will increase. With the demand for reliable service, switches will continue to play an important role in smart grid and distribution automation project implementations. Switchgears will be required to sense current and voltage and to work with controls to make decisions and function automatically in response to preprogramed customer parameters. Whether required for automatic power restoration or automatic transfer, switchgear will become smarter to meet the needs for reliable service.

Power Grid supplies High-Quality Glass Insulators Used in The North American Electric Power Grid

 Insulators are generally made of glass and ceramic material. It is used to fix wires to poles, and to insulate wires and poles. Insulators are one of the key components of high voltage transmission lines, and their performance directly affects the operation safety of the whole transmission line. Glass insulators manufactured by Power Grid are widely used because they are easy to maintain. In the early years of production and operation of glass insulators, it is found that they have the following advantages over insulators made of other materials.

The surface of the glass insulator is not easy to crack because of the high mechanical strength. The electrical strength of the glass is usually kept unchanged throughout the operation, and its aging process is much slower than that of porcelain. Thus, the glass insulators are largely discarded because of their self-damage, and they occur within the first year of operation, but the disadvantages of porcelain insulators are only discovered after several years of operation.

The use of glass insulators can cancel the live periodic preventive tests of insulators during operation. This is because every damage to toughened glass will cause damage to insulators, and it is easy for operators to notice them when they patrol. When the insulators are damaged, the glass fragments near the steel cap and iron foot are jammed, and the mechanical strength of the remaining part of the insulator is enough to prevent the insulator string from breaking. The self-destruction rate of glass insulators is one of the most important indicators of its quality. It is also the basis of the quality of the bidding evaluation of power transmission projects.
