How can we calculate the cable size???
plz give the formula !!!!!

Answer Posted / prashant

The basic equation is

P = 1.732VIcosA, where CosA can be taken as 0.85
V = 415 V
P = load
From this u have to find the current I and then using the
table select a suitable cable and cable size which can
withstant the current.

What are factors to be considered while we selecting the Core Balance Current Transformer for Earth fault protection

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?
