1) Can anyone give me a typical value for Insulation Resistance of 11kV xlpe cable? 2) How much will the IR value decrease per KM of cable length added?
what is meant by k-rating in isolation transformer?what is k9, k14 stands for?
Hello sir, pls send me hpcl technical test papers .i am. Appearing for the exam.
power formula
In an electrical power supply,why if neutral phase of a 3phase supply fail over current occur but if it's single phase supply neutral phase fail low current occur?
If you know per phase current and phase to phase voltage; what is overall KW of the circuit?
