  • Page 7: Safety Information

    ABB Substation Automation Technical Reference Manual REJ 527 Products and Systems Safety information Dangerous voltages can occur on the connectors, even though the auxiliary voltage is disconnected. National and local electrical safety regulations must always be followed. The frame of the protection relay has to be carefully earthed.

  • Page 8: Instructions

    3.1. Application The directional earth-fault relay REJ 527 is a secondary relay that is connected to the voltage and current transformers of an object to be protected. It is designed for earth-fault protection and supervision of distribution substations. Other application areas are protection of generators, motors and transformers.

  • Page 9: Configuration

    ABB Substation Automation Technical Reference Manual REJ 527 Products and Systems 3.3. Configuration Setting and connection example The appropriate configuration of the output contact matrix enables using the start signals of the earth-fault current and voltage units as contact functions. The start signals can be used for blocking co-operating protection relays, for signalling and for initiating autoreclosing.

    ABB Substation Automation Technical Reference Manual REJ 527 Products and Systems 4.1.1.3. Inputs The relay includes two energizing inputs and one external binary input controlled by an external voltage. The function of the binary input is determined with selector switches of the protection relay.

  • Page 12: Self-Supervision

    REJ 527 Technical Reference Manual ABB Substation Automation Products and Systems 4.1.1.8. Self-supervision The self-supervision system of the relay handles run-time fault situations and informs the user about an existing fault. When the self-supervision system detects a permanent internal relay fault, the ready indication LED starts blinking. At the same time the IRF relay that is normally picked up drops off and a fault code appears on the display.
