How are high power relays tested for reliability and performance?

This test is performed to measure the resistance of the contacts when closed. The test ensures that the contacts are conducting efficiently and are not causing a voltage drop across the contacts.

This test is performed to ensure that the insulation between the contacts and the coil is sufficient to withstand high voltages. The test applies a high voltage between the contacts and the coil to check the insulation resistance.

This test is performed to determine the number of cycles the relay can withstand before failure. The test applies a specified voltage and current to the relay and cycles the relay on and off repeatedly to determine its life expectancy.
