what is meant by line voltage and phase voltage in a three phase transformer?
pls tel me the electric train traction motors name plate details like rpm,torue,voltage,amps,watts..ect..
what is unbalanced rotating magnetic field?
What happens to voltage when current through the inductor is constant?
1) Why distributiion system decided 11 kv, 33 kv, 66 kv, 132 kv, 220 kv, 400 kv, 2) In 3 Phase line terminal of capacitor, why used for power factor improvement. 3) Why used rating KVA in transformer?
Hello, I am just preparing my self for a university interview and struck on the 11kv ring main unit system network. I just know that ring main unit has total three breakers, fuses and use to supply a power to any load/ building without any interrupt. But i am not be able to visualize the connections, either Ring main unit getting power from two different power sources? or there is always one feeder in complete ring circuit??? I would be highly thanks full of you help me.
why should the primary of transformer be connected in delta in a heat run test?
where used of HVDS system.
why the measure taken in multiplication factor of 11for voltage like.. 110V,220V,440V,1.1KV,6.6KV,11KV,33KV,66KV,110KV,132KV,220KV
Why we use CT on differant phases of 2ph.PT detection for brush-less static excitation of 3ph.,400v Synchronous Generator? What happen if use CT on same one of VT phase?
ow can i get certificate of competency as electrical supervisor and my diploma in electrical engineering from jalgaon.
Why is it that variation allowed in supply voltage to motors is (+ or -)10 %, whereas that in frequency is (+ or - )5 %
