Answer Posted / michael aliganga
CABLE FACTORY AC TEST VOLTAGE =2E+1kV= 2X35+1= 71kV
DC HIPOT TEST:
CABLE INSTALLATION TEST DURING AND AFTER = ET= EF X 1.8 X 0.8
ET = 71 X 1.8 X 0.8 = 102kV, ICEA DC FIELD TEST VOLTAGE
(ICEA S-97-682) IS 100 kV FOR 35 KV SHIELDED POWER CABLE.
EF=CABLE MANUFACTURERS RECOMMENDED FACTORY AC TEST VOLTAGE
IF NOT AVAIABLE USE 2E+1KV
1.8 AC TO DC CONVERSION FACTOR (QUITE COMMON)
0.8 CONVERSION FACTOR FOR DERATING FROM FACTORY TESTING TO
ACCEPTANCE TESTING.
