Hello Colleagues,
We have a 3phase monitoring relay(ABB CM-PAS) is being failing very frequently. The auto reset function is not working and I have to raise the Asymm settings up to 20% to reset the alarm and return it back to the desirable value. This issue was repeated in more than 6 relays in different locations.
Did anybody face similar issue before? Is there a recommended reliable type to be used instead on the above mentioned type? Is the digital monitoring relay is better to be used that the analogue ones?
Regards,
Mahmoud Diaa
