AS HI POT TEST IS CONDUCTED IN DC SO APPROX. 1.5 TIMES OF
AC SUPPLY VOLTAGE IS APPLIED FOR 1 MINUTE.
FOR 33 kV CABLE APPROX. 50kV FOR 1 MINUTE WILL BE APPLIED.
FOR TESTING OF "R" PHASE WE HAVE TO SHORT "Y" AND "B" PHASE
ALONG WITH ARMOUR & IT SHOULD BE EARTHED. SIMILARLY FOR Y &
B PHASE.
AFTER EACH PHASE TESTING IT SHOULD BE DISCHARGED THROUGH
DISCHARGE RODS.

(2E+1)1.414=dc
2E+1 =AC

(2*33000+1)1.414=DC
67000*1.414=DC
94738v=DC (it is a 100%)
but apply in 80% only it is standard for 33kv cable
APPly voltage dc=94738*0.8=75790V
(75.790KV DC)

2E+1KV=67KV FOR AC VOLTS
(2E+1KV)*1.414=94.73KV FOR DC VOLTS
ACCORDING TO IEC60950 STANDARDS.

For DC Hipot test the applied voltage calculating formula is equal to (2E+1000)*1.414*(80/100)
E = system voltage
1.414 = For DC RMS conversion.
80% = test conduct in site at second time.

For DC HIPOT = 1.414*(2E+1)
E=33/1.73=19.07
DC Hipot = 1.414*(2*19.07+1)
55.34kv approx 56Kv

For 33 KV cables we do three tests.

1. Vlf Test: We apply 10 kv dc between graphite and armour
at a low frequency (normally between 0.02 hz to 0.05 hz)
for 1 hour.

2. Insulation Resistance :- We apply 5 kv dc for 1 min

3. High Voltage ac Test:- We apply 57.1 kv for 30 mins
(33/1.732)x 3 = 57.1 kv

God Bless
