The REF 543 feeder terminals can be used in different types of switchgear, including single bus, double bus and duplex systems.
The protection function also supports different types of networks, such as isolated neutral networks, resonant grounded networks, and partially grounded networks. Applications also include protection and control of medium-sized three-phase asynchronous motors and shunt capacitor banks for reactive power compensation. In addition to protection, measurement, control, condition monitoring and general functions, the REF 543 feeder terminal is equipped with a large number of PLC functions to integrate multiple automation and sequential logic functions required for substation automation into a single unit.
Data communication attributes include the following communication standards: SPA bus via SPA-ZC 400, LON bus, IEC 60870-5-103, IEC 61850, Profibus DPV1 via SPA-ZC 302, DNP 3.0, and Modbus communication with more advanced devices. In addition, LON communication and PLC capabilities minimize the need for hard wiring between feeder terminals.
