1KVA transformer of different frequencies of
50hz,100hz,500hz&1000hz. which one of these transformer has
big size? Give reason

Answer Posted / rahul

The EMF of a transformer at a given flux density increases
with frequency.By operating at higher frequencies,
transformers can be physically more compact because a given
core is able to transfer more power without reaching
saturation and fewer turns are needed to achieve the same
impedance.

So, 50Hz transformer will be the bigger one.

How to perform a DC resistance test In Alternator and their proceduces?

We have drive feeding an output contactor for a 5000 hp motor @ 5kV application. The motor FLA is 629amps x 1.25% service factor = 786.25 amps The cable that we current have in place between the drive and the output contactor is 350kcmil- MV-105 (parallel cables). Per the NEC table 310.60 (C) (69). This show the cable ampacity is at 615 amps per cable for a rating of 1230 amps. We have derated the cable for the cable tray and the multiple cables application and our calculations show that after the correction factor factor we are at 922amps. 1230 amps x .75% correction factor factor = 922.5 amps. The customer is driving us to then use another safety factor of .25% off of the already derated cable. Can you please provide a longhand calculation for your solution on this application?
