230v DC is more dangerous because it does not has zero
crosing i.e contantly 230v is coming ,but in the case of
230v AC the voltage vary bw 230 to 0 -230 so it is less
dangerous compared to 230v dc

Answer / sharma punk

DC is more dangerous than the ac................




if you any dought than call me................

Answer / yano

by the term DC direct Current or direct to kill you! unlike
AC Alternating Current or kill you or after sometime not t
kill you it will just throw you away.. lol

Answer / faizal

230 v dc is
dangerous . Because
Rms value of 230 v dc
is 230 v itself,but
230 v ac is less than
that.

Answer / sssss

22ov ac is dangerous

in an open circuit. test there is no load curent.. but secondary. ia open then no urrent have to flow but there a smaller current flows why?

How much allowable difference current between on three phases Dear sir, We have a 1870 KW HT motor, 11 Kv supply,FLA-120A,2870 rpm,2-pole squirrel cage induction Motor.And stator is connected in star connection with Liquid resistance stater to limit the starting current.It has coupled with Centrifugal air compressor.My question is it is loading 73% of FLA taking R-phase 86.7 A, Y-phase-85.4A,B-phase- 78.3A.why the B phase current is that much of difference.Is it allowable, or any one tell me how much allowable current.If any method to calculate.

Can we inject more current in ct primary paralleling 2 loading transformers/Injection kit at a time?let ct ratio be (5000/1A)(per kit rating 2000A range),i need to inject 5000A,if this cant b done means wat is d optional?

We have .ht motor which is 60Hz.we run on 50Hz.so that it's speed reduce but we had one prob.that motor winding temp increase up to 135 deg.we want reduce this temp.what to do?we arrange ext.cooling fan but not much effect.we want reduce this temp. Inhouse without affecting much.cost. also don't want reWINDING OF MOTOR?
