Different types of Transformer Faults
A transformer is a device which helps with the transmission of electrical power, it is a static device without any rotating part and is totally enclosed. So the transformer plays a major role in the electrical distribution so the protection of transformers is an important process. The transformer must be protected from faults in order to do effective power distribution. What are the types of transformer faults 1-Over heating Over-heating is caused due to sustained overloads, short circuits and in case of failure of the cooling system, Overexcitation if a transformer is operated at its maximum potential like high frequency or in high voltage the core will get excited. Protection - Resistance temperature indicator can be used near the winding, Thermal overload and temperature relays can be used. Bridge circuits can be used when the bridge is unbalanced more than the permissible duration circuit breaker trips. 2-Winding faults The winding faults are internal faults, over-heating or mechan
