Answer / s.k.mishra

yes,the turbogenerator will operate on leading power factor

Answer / hareesh

Turbogenerator is a synchronous generator and it can work in synchronous condenser mode also. When it is over excited, the generator will operate with leading powerfactor.

Answer / kasa

tg can operate in leading p.f mode when it is under excited
condition but it is not advisable beczuse stator ends get
over heated due to leakage flux.

If we connect a motor and generator together (I mean that the generator gives the motor electricity and the motor gives the generator movement) regardless the losses. Will the generator still generate and the motor still move?

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?
