1 2795what is an isolation transformer??? what is its purpose??? what happens if it is not used where it should be used?????
2 5088how does the terminal voltage of transmission lines increase when a capacitor is connected???? This happens not only in transmission lines but also in all circuits. How??? When a capacitor is connected in a transmission line, capacitor also takes energy from the same supply. But how is it able to increase the terminal voltage??? Practically What sequence of events happen during increase in voltage???
2119How seriving & testing of the HT & LT breakers are done. What are the standard Ir values on which we can come to know the test is passed or failed?
1988what are the standard IR values should be of R-E, Y-E, B-E, R-Y, Y-B, B-R of VCB in closed condition and in open condition for 500KVA & 1000KVA transformers. and what is the acceptable range when tested by 5000V megger.

We have a distribution transformer of 750KVA/11kv/440v and an AVR (Servo Stabilizer) of 750KVA on the LT side of distribution transformer. Also we have an ACB of 1200A on the output of distribution transformer (that is on the input of AVR). We want to have an MCCB on the output of AVR. What should be the rating?
