How do you calculate 3ph AC motor power?
250 kVA generators come in different voltage settings and this information is needed before a wire size can be given
question is incomplete, I think you ask how much current consumed by this motor. for starting this motor we need a star/delta starter and a three phase supply.
400 amps
The basic dimmerstat is meant for operation from a nominal input voltage of 240v 1ph ac & can give output voltage anywhere between 0 to 240v or 0 to 270v ac by simple transformer action. Three such dimmerstats connected electrically in star and mechanically in tandem, become suitable for operation from a nominal input voltage of 415v 3ph ac and can give output anywhere between 0 to 415v or 0 to 470v.
How do you calculate 3ph AC motor power?
Ph such a three phase is 3Ph for example
It will not work at all.
In most applications 200v is easier to get for a supply voltage than 380v.
The 3PH motor has no internal contacts for a centrifugal switch and are therefore more durable when switched on and off frequently,
Yes.
2-3ph
Industrial and commercial buildings typically employ 3-phase, 4-wire electrical service due to their higher power requirements. This type of service can support heavy machinery and equipment that require three-phase power for efficient operation.
power , P=1.732*V*I*power factor so, the formula for calculate the load current for a 3 phase motor is,I=P/(1.732*V*power factor)
Yes, as long as you use only one phase of the 3 phase system. If R & Y gives 460 volts, use R & Y. This not a good approach though.
When 3ph transformer of required capacity is unavailable in that place 3 single phase bank is used. More over this bank works well in conditions where there's unbalance of loads. When there's quite small 3ph load you can isolate one transformer to create open delta connection. In bank nd single 3ph transfo's there wont be any change in maintaining phase shift
Sir, The rating of ac generator is always calculated in KVA.So rating of generator as asked in your question is 360 KVA Sir, The rating of ac generator is always calculated in KVA.So rating of generator as asked in your question is 360 KVA
