How often does relay protection occur
Many operators carry out secondary injection annually to ensure relays that protect circuits against overloads or faults operate appropriately. For example, unselective protection operation during a medium voltage network fault will cause an outage for an unnecessarily large number of consumers. Relay protection is often misunderstood as a. PSM represents how many times the actual current is above the relay's current pickup setting. When a relay malfunctions or fails, the costs can be severe: equipment damage, safety threats, and even prolonged power outages.
