What is reason of rating of transmission line multi pal of 11
like as 11/33/66/220 ? Why not use 75 kv 23 kv line in power
please tell me how a surge protector work on a DC 48Volt.?
please describe briefly.
Trafo ratio is 11kV/6.6kv,Vector group is YND11. What will
be the effect if secondary is used for earthed system.
What size cable (based on voltage drop) is required to
supply a 40 A three phase boiler if the wiring system is
75V single insulated cables installed in non-metallic rigid
conduit 56m from the main switchboard? Voltage drop in the
consumer's mains is 8V.
what is the formula of starting current of 3phase and 1 phase
I have an existing old MCCB. ABB Model SACE, the rating
are: Ue = 660 volts, Iu =1250 Amps, 3 poles, Ith (max) =800
amps at 45 deg C. I need a circuit breaker for my 3 phase
motors, 380 volts 60 hz. the supplier required the minimum
ampacity of the breaker to be 911 amps. can i use this
breaker with rating of Iu =1250 amps but Ith = 800amps
In case of generator when we consume more power produces by
it why load on generator increase and starts sound more.
and how it is adjusted..
