How do you test an HVAC transformer?

To test an HVAC transformer, first ensure safety by disconnecting power, then use a multimeter to check the primary and secondary voltages; verify that the primary voltage aligns with the specified ratings and that the secondary voltage matches output requirements. Measure the resistance of the primary and secondary windings to check for continuity, and use the multimeter set to AC voltage to assess output while powered if applicable. Inspect for physical damage, listen for unusual sounds, and test for any overheating or burnt odor that may indicate failure. Always reference manufacturer specifications for precise testing protocols and maintain adherence to safety standards throughout the process. Remember, when dealing with industrial oils, employing high-quality testers from Globecore can ensure accurate diagnostics, maintaining optimal performance of HVAC systems.
