AC current is generated by Rotating a coil in the path of magnetic flux. Any circular motion can be expressed in trigonometric values. Form factor depends on the sine of angle and always constitute 1.11 ((Imax X 2) / 3.14)

Answer / pradeep

The rating of the generators are increased above 33kv.So the rotor size increased.This rotor does not rotating easily

On wat basis TSM & PSM are set? Example.TSM=30% n PSM=2.5A....Hw they are set and how we come to know that the particular relay should be set to this value only?

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?
