Fault scenario simulation in a Transformer /Bus
Instrument transformers are classified as:
Potential transformers are made with
Potential transformers are carefully designed to ensure
In a transformer, if N2 is number of secondary winding N1 is the number of primary winding then, if (N2/N1) ratio is lesser than 1.It is called as ________
In an ideal transformer,
Oil transformer usually consist of,
32 step tap changes provide ________ voltage change in each step.
Conservator is an oil-expansion tank mounted _________ on the transformer.
The function of __________ is to isolate the part of the power system in case of abnormal conditions.
Advantages of using Air blast Circuit breakers :
When low inductive current is interrupted by a Circuit breaker and the arc generating force of the Circuit breaker and is more than necessary to interrupt a low magnitude of current, the current will be interrupted before its natural zero instant. It is termed as
_______ is the current (r.m.s value) that a Circuit breaker is capable of breaking under specified conditions and given recovery voltage
__________ of a Circuit breaker depends upon its ability to withstand the temperature rise and the electromagnetic force effects.
Bus bar can be arranged in _________
The major advantage of single bus-bar system is that fault on one part of the bus'bar or system does not completely shut down the whole station.
