Voltage Relay VR-100

Voltage relay VR-100 is a multifunctional numerical relay used for busbar voltage monitoring in low and medium voltage plants. Relay VR-100 detects voltage deviation from set-up values and according to selected delay performs signalling and/or circuit breaker trip. Voltage relay VR-100 monitors unallowed voltage disturbances and its main application is generator and transformer protection. Relay can perform two stages of undervoltage and/or two stages of overvoltage protection. Relay measures phase voltages, line voltages as well as residual voltage.
