Three-phase voltage relay SPAU 130 C
ABB SPAU 130 C THREE-PHASE VOLTAGE RELAY
The three-phase voltage relay SPAU 130 C is intended to be used for over- and undervoltage protection and supervision in distribution substations. The relay can also be used for over- and undervoltage protection of generators, motors and transformers. Generally, the relay measures the three phase-to-phase voltages of the system, but it can also be programmed for single-phase measurement.

The overvoltage stage can be given definite time characteristic or inverse time characteristic. The undervoltage stage features definite time characteristic alone. An external control signal can be used to block the operation of the undervoltage stage. The relay forms a whole including over- and undervoltage stage as well as flexible trip and alarm functions.
