Lightning/Surge Arrester meter?

Pufferphish · May 8, 2018

Hi, saw what look like meters at the bottom of some lightning arresters for a transformer in a main outdoor substation. I've never seen them before, anyone know what they are or used for? Some sort of sensing or indication if there is a surge perhaps? Thanks!

This appears to be some sort of surge counter and/or AC leakage current monitor for the arrester.

It is a surge counter that increments when a surge over voltage or over current is exceeded.

for everything about transformer click Transformer - Share - PCBWay. Read through well and you will get to know the purpose of each and every part of the transformer. Thanks.

It's a surge counter.

You can learn more about transformers and it's parts with their functions here: Introduction to Transformer - The Engineering Projects

There are also several resources online you can learn about transformers from.
