How do you perform transformer testing?

To perform transformer testing effectively, start by ensuring safety protocols are in place, including disconnecting power and using appropriate personal protective equipment. Then, utilize a transformer tester, specifically designed for industrial oils, to assess insulation resistance, power factor, and winding resistance. Connect the tester to the transformer’s terminals and follow the manufacturer’s guidelines for conducting routine tests. Essential tests include insulation resistance measurement, turns ratio testing, and voltage withstand testing to evaluate the transformer’s performance and identify any potential issues. Proper diagnostics can prevent failures and prolong the lifespan of the transformer, ensuring optimal operation. It’s essential to document all findings accurately for future reference and maintenance.
