6 MVA transformer secondary is rated for 725V at no load.
The incommer ACB is rated at 690 V, 3200 Amp. Would there
be any effect on performance of ACB due to lower voltage
rating?

ACB is not suitable as transfomer secondary voltage level
is higher than ACB voltage level which cause insulation
failure of the ACB and cause of flash.

How to calculate the time setting for star connection in star delta starter? For example 10KW 3PH Induction motor.
Why we used 690V in ACS 800 drives.Why dont use standard voltage like 415v or 1.1Kv
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?

Why reactive power is needed in a power system? How is it being absorbed or delivered by alternators? For reactive power control we are changing excitation but reactive power absorbing or delivering related to stator. How these two are interlinked? i want a detailed explanation with necessary expressions and figures?
