Transformer testing with Multimeter

In this tutorial, I have explained how to test step down transformer using the digital multimeter. This is not an accurate method of transformer testing, but with this method you can identify the high voltage and low voltage winding (Primary & Secondary) of the transformer. Also check the isolation and winging by measuring the resistance and continuity test.

In this tutorial video, I have shown practically, how test a transformer using multimeter.

I have covered the following details in the video:

  1. How to identify the primary and secondary [high voltage & low voltage] windings.
  2. How to check the transformer using a multimeter.
  3. How to calculate the turns ratio of a transformer.
