How do you test a 24V transformer?

To test a 24V transformer, first, ensure that the power is disconnected and that you have appropriate safety equipment. Utilizing a multimeter set to the AC voltage setting, connect the probes to the primary side of the transformer, applying power momentarily to measure the input voltage. Next, switch the probes to the secondary side to check for the 24V output. If the voltage is within the expected range, use the multimeter to check for continuity across the windings to ensure there are no open circuits. Additionally, inspect for any signs of damage or overheating, which could indicate issues. It’s crucial to follow all electrical safety protocols while conducting these tests.
