What are The Reasons of Failure of Transformers?

The electrical transformers are complex in nature. They require synergy of a number of systems and regular maintenance for operating the transformers at full capacity. But the question that comes up in the mind is why do the transformers sometimes fail? When we talk about determining the weak link that caused the failure in transformer isn’t easy. There are other factors too that might cause failure and that includes electrical defaults, lightning or even human error. But now as the maintenance standards have improved, thus, it can help in preventing the failures and detecting them before any damage becomes permanent in nature. 

The top transformer manufacturers in India listed the below mentioned reasons for failure of transformers which are as follows:

·         Aging of the transformers: While judging the cause of failure of the transformer, the age of is the most important factor that is listed down. If the transformer is old for more than 15 to 20 years, then the damage may be due to wear and tear. 

·         Insulation degradation: Another reason for failure of distribution transformer is the high temperature. Generally, high temperature of the transformer weakens the insulation system. The weakening of the system happens at a rapid speed and it causes overload. Overloading causes overheating and this causes the cracks in the insulation. If we conduct regular tests and maintenance, then it will help us in detecting the issue at an early stage. 

·         Moisture absorption: Next reason that can contribute towards the failure in transformer is moisture in the transformer oil. For detecting this issue, dissolved gas analysis should be performed regularly so that it can be judged out whether the oil is contaminated with gas or moisture. It further judges the type and amount of contamination and would help in determining of the type of fault.

·         Electrical or mechanical failure: Most of the times, there are damages in the parts or physical displacement of the transformer. This mostly happens due to a number of reasons and this includes normal faults and also the seismic activities. By taking early preventive and maintenance measures can help you in preventing the mechanical failures. The early diagnosis tests involve Sweet Frequency Response Testing and induced voltage testing. If the partial discharge is present at the time of voltage testing, then it shows that there is some sort of mechanical failure.

Safety Measures for the Transformers

Transformers are more than a device that works not only as a power saver but also it is designed in a manner that smartly supplies the power to a number of electronic applications. As it is designed in such a manner by transformer manufacturers in India, thus it is much important that you look after the survival of this giant device. While purchasing it from the transformer manufacturers in India, it is vital that you look into its minor details. After the installation, it’s vital that you apply some of the safety measures from time to time so as to reduce the possibilities of damages in the working areas. 

This article greatly focuses on the safety measures of the transformers. Let us look at it one by one!

·         Inspect transformer timely: Inspecting the transformers on a regular basis can prevent the sudden occurrence of breakdowns. While at the time of inspection, all you need to do is to check for any pungent odor of burning, look for any loose parts, any damaged cord or connectors and so on. By going through all these safety measures will give you a satisfaction that everything is under control. Also, keep in mind that you keep the power button off while checking the transformer. 

·         Monitor the power leakage: If you want to get the 100% of the supply of power, then you need to ensure the fact that there is zero leakage of power.

·         Avoid overloading: The transformer manufacturing company in India applies a sticker on each and every transformer to show how much voltage it can bear. Thus, if you exceed the prescribed limits of voltage, then there are chances that it gets damaged. Thus, it is recommended that you do not overload it. For taking the benefit of transformers for a longer period of time, it is important that you use it at an optimized level. 

·         Keep the transformer and its component dry: For taking advantage of the transformer for a longer course of time, you need to keep the transformer and its component completely dry and free from any sort of moisture. By this, it will reduce the chances of short circuits. 

According to Tesla Transformers Global Private Limited, you need to make sure that you check the working of the transformers from time to time so that there are less chances of damage.

3 Reasons for Failure of Transformers

When we talk about big-ticket items, then special transformers in India would surely top the list. There are a number of transformer manufacturers in India who are regularly supplying the business units with special transformers for their needs and requirements. So, when they fail prematurely, we feel way more frustrating because all our works are dependent on the transformers. And the damage that occurs in the transformers is far more than the replacement. Also the added expenses that includes in the failure of transformers are loss of production time, damaged credibility and regulatory fines. 

In this article, huge emphasis is laid on the reasons for failure of transformers. Typically, there are three major reasons that contribute towards the failing of transformers and those are as follows:

·         Craftsmanship: While looking for buying transformers from transformer manufacturers in India, you should go for the ones which offer you cost effective solutions and not the cheap ones. Obviously, cheap transformers would cost you less but would cost you with sudden failures and damages in the components in the longer run. The main factor that plays an important role in the life of the transformer is its craftsmanship that went into building it. While most of the people ignore this level of attention and they rush into buying it without looking at the minute details. Thus, they usually have to encounter with the failure of their transformers in the longer run. 

·         Materials: After the craftsmanship, material is the factor that plays an important role in construction of the transformer. According to transformer manufacturers in India, the thing that matters the most is using of the right wires and insulating materials. This contributes towards running of it in longer time. It is important that you look for the winding materials too. Thus, material quality is the second most important factor that shouldn’t be overlooked.

·         Design: Whether you go for dry or special type transformers, the way in which the coils are wrapped around the transformer’s core is the important thing that should be looked. It is due to the axial forces that are acting at the corners of the rectangular transformers, the energy gets wasted and the noise is created. And if the designs are in round-wound, then voltage stress is much lower and they stay quiet, run cooler and also prevent the risk of short-circuit.
