Answer Posted / kalyan chekuri

I have a system which had 400kV 100 MVA/11 kV 50 MVA/11kV 50
MVA transformer whose secondary is earthed with NGR of 300
Amps. I have bought 18000 Km of 11 kV earthed cable to lay
on 11 kV side of it. If the phase to earth voltage is 6.4kV
and root 3 times is the voltage expected to go up i.e 11kV,
why cant it be used if the power frequency withstood for
17kV for 5 minutes

Dear Mr B C pal...Can you plz. put some light on principle of operation of Z-Ct in conjunction to its use with 1Cx1000Sqmm HT Cables & Directional Ground Fault / Over Voltage Relays...Regd..Parag v K 9899115632
