WebPhase monitoring relays protect against equipment failure caused by faults in a 3-phase system, such as phase reversal, phase loss, phase unbalance, overvoltage and … Web1 de jan. de 2024 · When a breaker trip condition occurs, a timer starts. The phase currents measured by the breaker CT’s must drop below a preset value within the TD provided. For relay functions that do not require current above the pre-set value (these can include 24, 32, 64G, & 64F), then the breaker ‘52a’ contact must open within the TD provided.
