Re: FOR TESTING 33KV CABLE HIPOT TESTING.HOW MUCH KV WE HAVE TO APPLY .GIVE IN DETAILS.

Answer
# 1

AS HI POT TEST IS CONDUCTED IN DC, 25 KV SHOULD APPLY TO 
THE 33 KV CABLE

BECAUSE 

33KV X 0.707(RMS VALUE TO AVG VALUE CONVERSION) = 25KV(OPPR)

Is This Answer Correct ?

2 Yes

2 No

Answer
# 2

2E + 1 KV = 67 KV DC Hi pot
67 * .707 = 47 KV AC Hi pot

Answer
# 3

(2E+1)=67 kV FOR AC HIPOT ( 1 minute test)
67*1.7 = 113.9 DC HIPOT ( i minute test)

for aged cables generally we will apply 65% of the above

Answer
# 4

U0 * 4 = 33/ 1.732
           
        = 19.05 * 4 
        = 76KV
