GIS BUS BAR HIPOT TEST

GIS BUS BAR HIPOT TEST
I am going to do Bus bar hipot test
Before going into Test we have to check the following things
1. Open earth switch.
2. Rack out VT
3. Check The barricade around Testing Area.
4. IR test has to conducted before hipot testing.
5. Check the humidity of the place.
In GIS we have to use a special termination cable for doing hipot
In this video i have show only for Y phase hipot full video without cut and editing

What is the permissible leakage current for a successful Hipot of 33 kV GIS?

[@khawajaadil4780]

there is no certain value of leakage current . actually it depend the no of switch gear under test. i will explain you more . if the leakage of one no swg is 10 ma then suppose your switch gear is of 4 no then obviously the leakage court will be 4X10 =40 ma and so on for 10 no switch gear it will be 10X10=100ma. Generally it depend upon the bus bar length. longer is the length higher is the leakage also note down that the capacity of the test set is very important . as the leakage current is coming from the test set now you calculate the capacity of the test set. suppose the you are excepting current 100ma at 70 kv then the capacity of the step up transformer will be 0.010X70000=7000watts=7.0 Kw. so in size du to high insulation it will be of big size and it be difficult to build and hence cost will be more. Now come to the point the high voltage test is a "go" or "no go" test as for as insulation is not break down the test will be declared pass the amount of leakage current is not a deciding factor.

once i go to site i will make bro

Hello can you tell me how to discharge the switchgear to ground

[@baranitech1026]

after testing we have to use discharge rod thank you.

[@miteshgorfad2637]

What is MA current following is abnormal condition???

[@baranitech1026]

there is now fixed value.

[@user-fq1ij3sn8t]

How much leakage current accept for AC Hipot test?

[@baranitech1026]

there is no fixed value. need to ref. FAT

[@eng_mohammadaljazairy4082]

What do you mean by IR test ?

[@baranitech1026]

to check the insulation level of the equipment

[@velusamypothiraj2300]

Is this AC hipot kit or dc hipot

[@nafeesakhtar796]

Hi sir
How DC Hipot???
but the formula you used here is of AC Hipot 80%Vp plz explain??

[@user-fq1ij3sn8t]

Busbar Hipot test AC, cable Hipot test DC used. 2E+1 80 % kV accept for 1 or 5 minutes depend upon on customer Requirement.

@@user-fq1ij3sn8tSO,HERE AC HIPOT BEING TESTED, what about dc HIPOT voltage limit

[@ajithrojaajithroja]

Need to give 2.2 times of rated voltage of bus bar in highpot test

[@baranitech1026]

depends on they country standard
