What is ANSI 46 Phase Unbalance Protection Guide about?

Phase Unbalance Protection (ANSI 46) is designed to protect motors from damage caused by unbalanced phase currents, which can lead to overheating and reduced performance. It calculates the current unbalance as a percentage and trips if the unbalance exceeds a fixed pickup threshold of 30%, with different time delays for startup (0.7 seconds) and steady state (4 seconds). This protection cannot be deactivated and is active during both startup and steady state conditions.
