Voltage monitoring relay review. The voltage monitoring relay analyzes the power supply network and, if the network voltage exceeds the set limits, disconnects the load from the network. Once the voltage returns to normal (within the specified limits), the load is automatically reconnected after a preset turn-on delay. This delay is necessary for cooling systems (refrigerators, freezers), which cannot tolerate short-term power outages. How can I avoid refrigerator repairs?
