1 2146what is an isolation transformer??? what is its purpose??? what happens if it is not used where it should be used?????
2 4024how 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???
1591How 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?
1480what 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.
