Manual operation of 400 KV isolator opening.

Low voltage: you cannot break the circuit, no current will flow, you need to connect a wire"

High voltage: Fine, I'll do it myself.

It looks like those halos get all the damage, but it does seem that the switch could have been operated more quickly. The helmet should indeed have been worn.

Why there's sparking..? Isn't Isolator operated in off load?

[sarangsdeka]

Does any chance that the spark can harm the people whoes are under that circuit breaker at that time

[hibaworld]

What is the scientific explanation for this situation?

[_]

If circuit breaker trip then isolator opening this condition can spark produce or not ??

[sergeantjoenskafrostops]

This is not a isolator this is a dissonnect switch or breaker.
