BRIEFELY EXPLAIN MEGGAR PRINCIPLE
In DC current-excitation to transformer, why it sucks more current? Eventhough there is no power transfer between primary and secondary? R is very low so it should suck less current only na thn y its current increases?
DEAR SIR, HOW TO CALCULATE WELDING TRANSFORMER CAPACITY IN KW OR KVA (POWER). TWO WELDING TRANSFORMER USED WHAT TYPE OF DG SET CAPACITY LIKE ( 45 KVA OR 62.5 KVA), PLEASE TELL THE WELDING TRANSFORMER RATEINGS. I AM REFINARY (TANKS WELDING) THANKING YOU
If the capacitor bank is installed in switchyard say 132/22kv then on LT side say 22kv/0.433kv is it necessary to install capacitor bank for maintaining power factor. if pf is maintained on HT side then will that be maintained on LT side as well.if not then how&why??????/ please explain...........
How to calculate the Sizes of the cable required for one specific load? Is there any formula for that? ( EX: For 400KW load,50mtr Length, What is the LT cable Size required?)
how to calulate short circuit current for the following: 1.cable connecting 11KV of 22KV/11KV transformer to 11Kv of 11KV/415V transformer 2.what cable size should i use.
I want to know that a 160kva diesel generator contains capacity of 160kva on each phase like R=160 Y=160 B=160 total RYB=480kva or it is total capacity of all there phases like RYB=160kva ... thanks in advance ...

why always out of the 3 phase(RYB) of supply, in Y phase w.r.t the voltage is higher? on R & B phase the voltage will be lower as compared to Y phase?
A 10 kva ,400v/200V , single phase transformer with 10% leakage impedance draws a steady short -circuit line current of
