Answer Posted / tapan k ghosh
The output expected from a generator or transformer is
electrical output. Electrical output contains both active
and reactive components and hence these equipment are rated
in terms of composite power,kVA i.e.sqrt(active2+reactive2).
Output expected from a motor is motive power i.e. active
one and hence motor is rated as kW.

how to determine the inrush current of a transformer
Hello Friends, How can we recognize the CT Star Point is S1 or S2 in case of Electro Mechanical Relays and what is meant by Restraining coil in relays and what is the purpose of that.. thank you in advance..
What will be the size of copper cable (each for 3 phase and 1 neutral) from Service connection Kit-Kat to Panel Board (i.e. to main switch) for a 6 pole 3-phase AC induction motor of 200 H.P. capacity? Amp-255 A, Frequency:- 1450 rpm.
At the starting of dc motor and syn.motor and induction motor high current flowing through the winding. Due to this the windings burnt out. To avoid this different types of starters are used. But incase of transformer what Will be used (At starting no emf is induced in the primary winding)?

3 shows a 415 V, 3-phase generator supplying a 3-phase 415/110 V transformer. Draw the individual and combined impedance diagrams to a base of 10 kVA. Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
