Hi all,I have been asked to investigate the possibility to clean relay contacts by applying a voltage and a measured current to them.
I have been trying to find some some information on the subject but i had no luck.
The idea is to energize the relay whilst applying a voltage to the contacts.
I have tried this method on several relays and it seems to work.
However i cannot decide if is better to first energize the relay and then apply voltage to the contacts, or do it the other way round.
And then there is the question of how much current and for how long to apply it to the contacts.
I would appreciate any comment please.
