Overview of NVR Panel

Reliable Protection Against Voltage Failure & Phase Loss

An NVR Panel (No Volt Relay Panel) is a critical electrical protection panel designed to automatically disconnect power during voltage failure or phase loss and prevent automatic restart until normal power conditions are restored. This protects sensitive equipment from damage caused by single phasing, under-voltage, and over-voltage conditions.

AAVAD Instrument Pvt. Ltd. manufactures robust NVR Panels engineered for safety, reliability, and long service life across solar, industrial, and utility applications.

What is an NVR Panel?

An NVR Panel continuously monitors the incoming power supply. If any one of the three phases fails or voltage goes beyond safe limits, the No Volt Relay trips the incoming supply instantly. The panel does not reset automatically and allows restart only after all phases return to healthy conditions—ensuring equipment protection and operational safety.

How NVR Panel Works

• Monitors all three phases continuously

• Trips power supply during phase failure or abnormal voltage

• Prevents automatic restart after power failure

• Requires healthy voltage on all phases to reset

• Uses relay logic in combination with contactor, SPD, MCB, and Auto/Manual selector switch

This makes the NVR Panel ideal for critical electrical loads and inverter-based systems.
