|Why servomotor and induction motor are in different shape
|How to calculate load taken by a cable?
|Even when a particular generator in a generating station is
under maintenance we are still able to maintain the same
power output. How is this possible? Does the tie line
between 2 generating stations have a role to play in it?
|HOW TO IDENTIFY THE RELAYS WHICH APPLICATION IN WHICH RELAY
|in DG synchronization system can i short R,Y,B- phase(DG-1) to
R,Y,B Phase (DG-2), HOW IT WORK . WHAY WE NEED TO
|What is the distance b/w R&Y phase in 33kv T.line,11kv &440v
|What is the function of induction motor when low voltage is
|it is possible to run 130V AC and 230 V AC cables run in
|How to control speed of DC motor with AC power?
|what is the working difference b/w softstarter and
Variable frequency drive ?
|how the inductor will work on dc supply?whether it will
work or not?
|I have carried out wiring for lighting in a shed in
Industrial area which contains Metal halide lamps & have
balanced in 3ph.Now when we put all the lines on in the
daytime the current taken at 3phases at MCB comes to be
equal i.e.28,29,28Amps respectively but in the night time
i.e between 7p.m.to 11p.m. at the same MCb the current is
52,59,62Amp, though I have fit 63A MCB it is tripping in
the above period.What may be the reason.?
Note: This industry is located in industrial area where
majority of steel ingot manufacturing plants are there.
Whether this may be due to harmonic? what should I do to
overcome above problem.pl suggest urgently.
