Thanks🙏
Great explanation....thanks for sharing this
Very informative, thankx
Thankyou dear sir 🙏
for 11kV cables, how much DC voltage is injected for the test? is there any specific reference you use for this test to refer to? thanks in advance. 😁
10 kv DC is applied
Nice sir kooch testing ka aur video banaiye
thank u
Awesome bro
Thanks 🤗
Very good explanation
Thanks for liking
thank u
also tell in video if leakege current appear in device or cable how to trace it and how to troubleshoot the lekage current and how to set it?
please make a complete video about any test with full information
At the end i have seen HT clip is on cable end and earthing clip on other end of the cable actually that smaller clip should be grounded,since you are testing single phase respect to ground,This test set is meant for single phase testing only.There is another set for phase to phase testing.

Sir, Power cable have 11KV 3-phase AC supply, then how it is possible to give DC supply testing for this cable? Please let me know about this ..Little bit confusion sir ..
Sir ,what is the permissible value of leakage current
Sir, Folt ka kese pata chalta he. Folt hoga to kya hoga...
Sir solar penal ka hi pot test kese krte h
can we say the current as no load curreent that we get from the hipot testing
The hi-Pot test is used to evaluate the insulation condition of the test object. The Hipot test ensures that current will not flow from one point to another and indicates the ability of the insulation to withstand high voltage and over-voltage transient.
Hi
How to know that,current leakage or not
How much second apply for testing between phase to phase and phase to ground? Also, know me second side cable is open or not?
Applied voltage for 60 sec.
and another side cable terminal open
Sir how much cost for one day testing in site
Plz formula kya he hm kitina kv denge in 33kv cable pe
HT ka phase kha pr touch krnge ji
Sond nahi aa raha hai
The voltage applied is AC or DC to measure the leakage current?
DC
Why apply DC supply...???
When you apply a voltage between the core conductor and the conducting shield of a long cable, this cable is seen by the supply as a capacitor.
If you apply alternated voltage on a capacitor, some current will be drawn, which is undesirable for a HIPOT test, since HIPOT equipment usually have low current capabilities and it may be hard to differentiate the “capacitor” current from any eventual breakdown current.
When you apply direct current, after the voltage has stabilized, if some current is drawn, all of it is due to breakdown or leakage.
So , from above discussion we can see that insulation testing methods are designed to use DC voltage not AC
thanks for the info but i have a question since we are using hipot testing with the one terminal open(end terminal) how is the current is display on the display pannel
zero current
Why use dc High voltage for test
