Just wondering if anyone has any direct experience with use of the ABB light-sensing arc detection relay, REA 101/REA 103?
ABB has been promoting this in the US in recent months and it does seem to have some possible application in retro-fit applications where other arc-flash reduction methods would be much more expensive. But I'm always reluctant to recommend a new technology that I don't have any direct experience with.
Has anyone installed these on existing systems?
(I'm familiar with the relay and how it works - I'm looking for field experiences - either positive or negative)
TIA,
Dave
