Isolate and Connect to the Relay

You need to isolate the relay from the system and connect your test-set before you can start testing. This video shows you how.

What is expected operating time difference, when a protection element is configured to Form A and Form C type output?

Chris Werstiuk (Administrator) April 4, 2018 at 9:46 am

Not much. A couple of ms at best.

1. May I suggest that whenever you refer to input or output (I/O) do also specify whether it is I/O of relay or test set. My internal logic got messed up when you swing from input & output back and forth while looking at the relay, the test set and the circuit diagram. Sorry, my brain runs at really low speed.
2. I totally agree with the idea of simulating the relay output contacts or any device output contacts like the breaker/transfer trip contacts. Some of us test/analyze relays in the laboratory & simulation is the next best thing when site is not accessible.

Thanks for the comment.

1. I completely understand and try to distinguish between the two whenever I can.

Teng Shuen LIEW July 26, 2021 at 8:21 pm

Thank you.

Chris, do you know of any resources where I could get more in depth explanation on wet and dry contacts and wetting voltage? I have been working in the power industry for about 10 years, and I never had heard of these terms until I started working in substation control houses. I asked a veteran of the industry who is a EE & has his PE and does power flow study consulting work, and he wasn’t familiar w/ these terms either. So I know it’s not just me who’s in this boat. Thank you

I can’t think of any, sorry. Here’s a preview from our upcoming seminar about Basic Overcurrent Relay Testing (An Introduction to Protective Relays) that might help:
