insulation level

[etalaat]

What is the meaning of the insulation level of electric panel is 660 volt

 

[tom baker]

Your question is not clear, however it may be the maximum voltage rating of the system.

 

[etalaat]

I mean that insulation voltage of any electric panel or distribution board and how it can be measured

 

[coulter]

Do you mean: How would one test if the factory specified panel voltage rating is not compromised, like with a cracked insulator?
