How to find the length of a Xlpe cable required to transmit
3mva load at 22kv.
block diagram of 2 ups system connected in hot stand by mode?
Grounding. Dear all at one of my site we checked the amps at the earthing cable to the alternator it was found 125 to 130 A. at the neutal cable in same machine found 146A. in the same plant checked the earthing current on other alternator it was 52A, and neutral 116 A. we are facing problems with our controller and the card was damaged once. can that neutral/GND current be a reason? as there is common grounding for the Alternator,Brkr panel,Transformer?
for testing busbar (33kv) hi-pot .whether we can apply DC r not.and what is the test volt for that .explain
importance of air gap in transformer
what is relay
What is time response of the control system?
what is the diff. btwn. electronic regulator and ordinary rheostat regulator for fans?
Maximum efficiency occurs in electrical machines is at i)Full load,ii)50% of full load,iii)Near full load,iv)None of these
single phase voltage 230 and Three phase voltage 450 why 690 voltage
why battery dc voltage become Half when we check with respect to ground for example 120volts + and - terminals and when we check + terminal with Earth thats 60volts why 60volts same result on 24Volts and with ground 12Volts only expert answer that thanks we can not ground the battery.
what you mean by current? what you mean by voltage? what is difference between star and delta connection in motor side?
For these 2 devices what their power ratings are ? 1) single phase : AC 220V & starting amps 3Amps (i.e. starting torque) and the stabilized amps 2A ... For deep freezer 2) single phase : AC 220V & starting amps 2.7Amps (i.e. including the starting torque of a CRT monitor) and the stabilized amps 1 Amps thanks
