Any bad experences with arc flash relays 2

[cranky108]

Looking at reducing arc flash hazard's on older switchgear. What problems has anyone had with arc flash relays?

Is lightning a problem?
Dosen't the overcurrent relay solve that?

Do you leave the flash relay turned on all the time or only when someone is in the gear?

The ABB REA's typically can't be triggered by the built-in flash on a portable camera. You need an add-on flash. Already tested that one.

If a photographic flash won't do it, I hope the manufacturers are providing suitable test equipment.

A photograhic flash will do it but it can't be from a built in flash as LionelHutz noted. When I've demos or tests done, it was using a stand alone flash unit. This are the type that are bought for cameras that have an external flash mount, higher end type cameras.

Hello,
I've only good experience with the arc flash protection from VAMP.The CB trip is done to avoid unwanted trip (in my cases) with ARC Protection + OC detection.
If you visit
