  • 3 Basic Electrical Tests for Medium-Voltage Circuit Breakers

    Jul 26, 2016Using a test current less than 100A is acceptable, but know that equipment manufacturers usually dont recognize warranty claims based on a 10 ampere DLRO test. Measured resistance values should be within 50% of each adjacent phase, and comparable to similar breakers as stated in NETA Maintenance Testing Specifications. The resistance should
