You might have read about transformers, their types, and different methods of testing them. In this article, I have put down various kinds of faults that concur with the transformers. And how to reduce or avoid these electrical faults. Read on!
A transformer is an easy-to-use machine and is the main component for high voltage power transmission in any device. There are varied types of transformers, and each of them is used for many different purposes in the electrical system.
Know the Types of Transformers
Where are transformers used?
Transformers as said before is a machine that is the primary instrument to transmit high voltage current to other machines being used. Transformers play a prominent role in supplying power to various applications like:
A transformer is a machine, so it is sure to have specific faults. There are different types of transformer faults that may occur at different periods of particular situations.
Open Circuit Fault
An open-circuit fault happens when an electrical current circuit is disturbed by any electrical supply error. In the three-phase transformer, the error may see more than one phase or may occur between phases.
The overheat of transformers occurs in a liquid insulation oil transformer. The standard insulation rate for a transform is 220°C. If any time the temperature goes above the normal rate in the insulation, the transformer tends to overheat.
Winding Short Circuit Fault
But choose to travel through a shorter way. Winding short circuits are really common in electrical devices. A short circuit happens when the electrical current is not distributed evenly through all the wiring in the machine. That is why it is called a winding short circuit fault.
Faults Due to Lightnin
Lastly, faults occur due to natural calamities such as lightning. Power transformers are at risk of windings and bushing during lightning strikes. Due to this, there are many chances of stress on the insulation of the transformers. This is called dielectric failure and is the reason behind high-level damage in power transformers.
Oil Level Monitor Device
These were some common faults and safety methods used in transformers. I hope you got all the information and answers you were looking for! Keep coming back to Laxmi Associates.
