Schneider Electric PowerLogic™ P1V Voltage Protection Relay

The Schneider Electric PowerLogic™ P1V Voltage Protection Relay is designed to monitor and protect medium-voltage electrical systems against abnormal voltage and frequency conditions. It combines voltage protection, measurement, control and communication functions in a compact numerical relay, making it suitable for utility substations, industrial facilities and commercial power distribution systems.

The relay continuously measures system voltage and frequency to detect conditions such as overvoltage, undervoltage, overfrequency and underfrequency. When abnormal conditions occur, the P1V responds quickly to protect connected equipment and help maintain the stability of the electrical network. It also provides valuable system measurements and event records that assist operators during maintenance and fault analysis.

As part of the PowerLogic™ P1 family, the relay is available in multiple variants to meet different application requirements. It supports modern communication protocols for easy integration with SCADA and power management systems, while its intuitive interface simplifies configuration, commissioning and everyday operation.
