Phase monitoring relays are DIN rail mounts and are designed to Monitor operating voltage and phase parameters. Preventing damage to the connected equipment in the case of a fault or abnormal operating condition

Voltage monitoring relays are designed for either single-phase or three-phase systems. Those that are used in three-phase systems are sometimes referred to as phase monitoring relays.

Their primary purpose is to protect connected equipment from either an under- or an over-voltage condition and are designed to ensure the voltage remains within a predetermined bandwidth, with both high and low voltage limits.

GIC voltage monitoring device is designed with a programmable option of Under /Over voltage limits, In addition to limits on the allowable voltage, includes a programmable time delay (also referred to as a tripping delay) for which the fault must be present before the relay will trip. The purpose of the time delay is to prevent nuisance tripping from conditions such as momentary voltage dips (under-voltage).

When the operating voltage is within the maximum and Minimum voltage settings with the correct phase sequence for 3 phase, the relay is energized and the NO contact is closed, connecting the load. If the voltage exceeds the maximum voltage setting (sometimes referred to as the pickup voltage) OR Drops down below the minimum voltage setting including a hysteresis value (known as the dropout voltage) or phase reversal, the relay is de-energized, the contact opens, and power is removed from the load.

Three-phase voltage monitoring relays or phase monitoring relays monitor additional phase parameters along with over-voltage and under-voltage conditions: namely, phase imbalances, phase loss, and phase sequence (also referred to as phase reversal).
