We were installing a new transformer in our company. I want to know that do we need to test the transformer using megar?

 

Sensorless... good start! A myriad of problems can occur during installation.

Checking of Insulation Resistance (IR) using a Megger (Biddle or equal) Instrument, at the very least, will establish a baseline for future monitoring of insulation health!
