I mentioned this in a thread the other week,,, but now I've been asked to price the remedials so I need to figure this out.
I need to test an earth leakage relay which is set to 1A 0.5sec delay... My Megger1502 shows >600ms when I tested it last week, even when I turn the delay down....
So,,, is this a limitation of my tester,, is there a fault in the ELR?
Or is there another way of testing it that I can easily (relatively cheaply) use
