Answer Posted / kadiresan
The Potential transformer is designed such that it reduces
the system voltage such as 3.3kV, 6.6kV, 11kV, 22kV, 110kV
whatever is used into less voltage of 110V. This 110V is
used for metering and protection such as Over Voltage, Under
Voltage, Over frequency, Under frequency, Distance
protection, Transformer differential protection.... etc., as
per the substation requirements. Since there are both Indoor
and Outdoor Substations....

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?
