SAFETY CLEARANCES|BASIC INSULATION LEVEL|Sectional Clearance|EXTRA HIGH VOLTAGE SUBSTATION

[@e-powersolution7225]

I think section clearance should measure from the live point to person operating , kindly check once. 5:43

[@christopherbarber5228]

Thanks so much, very good recap.

[@SufiShahHamidJalali]

In your video at time 8.32 you have multiple values of lightning impulse withstand peak voltages like 450/550/650 kV for 132 kV system rated volage. Can you say why? Thanks.

[@shivanikoleti9917]

Wt is switching impulse voltage and lighting impulse voltage ...

[@travelingwithsun]

Ground clearance is basically the distance between ground level and bottom of any insulator as per IEC 61936.

[@thinkseeeatthroughvickus4555]

Is IEC 61936, will refer to the same clearance chart mentioned in video? ref: 8:55 mins

[@AmanKumar-jp1fd]

Please elaborate about testing of power transformers,,,,

[@Krishnasaini]

hi, do you work in any safety testing laboratory?

[@nitinsharma-rw3zz]

Hi good explanation. Please let me how we select gap in two equipment in same section.like gap between ct and cb

[@electricaltechnologyandind5335]

Specified in cbip manual

[@narenchauhan3241]

Thank You Sir..

[@himanshu2232]

Please make vedio on cb selection for substations.

[@electricaltechnologyandind5335]

Okay i shall try...

[@thinkseeeatthroughvickus4555]

can you advice where u took that clearance chart from?

[@electricaltechnologyandind5335]

Cbip, indian standard

[@thinkseeeatthroughvickus4555]

@@electricaltechnologyandind5335 will u share it please?

[@pramodgavit7666]

Please guide for Lt and Ht also

[@electricaltechnologyandind5335]

Ht and lt systems are mainly housed inside a panel. So the assembly could be type tested at lab. Hence there is no recommended clearance. Manufacturer designs as per their standard and make high voltage tests on that. If the system withstands the design is correct. Also these panel bus bars has sleeved insulation.

Please mention IEC reference no.

I found those figures in indian standard
