To test a high voltage transformer, first ensure safety by using appropriate personal protective equipment and following safety protocols. Begin with an insulation resistance test using a megohmmeter to check for insulation integrity. Next, perform a turns ratio test to verify the transformer’s winding ratios. Additionally, conduct a power factor test to assess insulation condition. Finally, if possible, apply a high voltage test to confirm operational capability, ensuring to monitor for any abnormalities during the process.
