noload

Answer / parimala
to calculate the P=root 3*line voltage *line current. By
substituting the values we can calculate fullload current
to know the no load current we have to know the RPM
usutken 40 % of full load currrent is taken on noload

Answer / partha
Simply take the formula of
KW = 1.732 * V * I * cos phi
ie
30 = 1.732*415*I*.8
[as voltage is 415v & in our country standard p.f 0.8]
I = 52.166 Amps

Answer / zahid
formula for no load current of 3phase electric motor
P= 1.732VI
I= P/1.732V, ur required result can be achived by putting
value in this formula

how much power consumed by 1.5 ton capacity split A.C in 1 hour
Main CT ration is 400/5, meter CT ratio is open type: -/5A. What is the Multiplying factor of the meter, considering same PT ratio.
I find that underground strip-armoiured,4core,LT PVC cables in an earthed power distribution sytem are occasionly found in charred condition-with no trace of it except ash. Is this because of no proper earth connection/continuity (giving rising to high armour resistance)in the joint enroute or because of insufficient capability (again due to high armour resistance)of cable-armour to carry fault current or due to neglected /unprotected overloading of the cable or due to high armour currents caused by power thefts where only phase(s) are unauthorisely tapped & at the point of poer consumption earth terminal is established by burring underground a not so good earthing rod (or using an underground water pipe for the purpose)
What is the Maximum Power generation capacity of a Synchronus Machine ??
After synchronizing the running generator with grid, the avr getting tripped and the generator breaker also oettong tripped, before tripping the avr the pf meter of generator is showing leading pf please kindly give a suggestion to rectify this problem.
can induction motor run over the rated speed ?
What is the difference between induction motor and the Synchronized one?
I want to give Power supply to a house from the Feeder, Total Load of the House is 128 KW, how to calculate cable size for this load ?
There are 2 motors without name plate and terminal but one is DC motor and another is induction motor.How one can identify which one is DC and which one is AC motor?
can we run a motor rated 50Hz,415vac,1440RPM At higher speed then rated on name plate with the help of VFD /drive on long term basis.wheater it will effect the motor life
How many types of Transformer testing..
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?
