Description

The REM 543 machine terminals are used as the main protection system of generator and generator-transformer units in small and medium-power diesel, hydroelectric and steam power plants. The protection for large and/or important MV synchronous and asynchronous motors used, for example, in pumps, mills and crushers during start-up and normal run, forms another application area. The protection functions of REM 543 are designed for selective short-circuit and earth-fault protection of rotating machines. Unlike most other power system components, rotating machines also need protection against abnormal operating conditions such as over-current, unbalanced load, over-temperature, over-voltage, over and under-excitation, under-impedance, over and under-frequency and generator motoring. For motor protection start-up supervision, there are also stall protection and cumulative start-up counter features. Scope Machine protection relay Product benefits Extensive protetion for motors and generators Programmable logic functions (PLC) Optical communication for fast disturbance-free communication Flexible connectivity and IEC 61850 support Certified for marine and off-shore use Product features Voltage and current measurement via conventional measuring transformers or current sensors and voltage dividers Support for IEC 61850 protocol through the SPA-ZC 400 adapter 15 binary inputs and 12 output relays and optional RTD

Application The REM 543 and REM 545 rotating machine terminals are designed to be used as anintegrated main protection system of generator and generator-transformer units in smalland medium-power diesel, hydroelectric andsteam power plants, etc. The protection oflarge and/or important MV synchronous andasynchronous motors used e.g. in pumps,fans, mills and crushers during start-up andnormal run forms another application area.The REM 54_ machine terminals as integrated packages make possible compactmarine environment solutions for unit protection, too. In addition to protection, measurement, control and condition monitoring and generalfunctions, the machine terminals are providedwith a large amount of PLC functions allowing several automation and sequence logicfunctions needed for substation automation tobe integrated into one unit. The data communication properties include SPA bus, LONbus or MODBUS communication withhigher-level equipment. Further, LON interbay communication, together with PLC functions, minimizes the need for hardwiringbetween the machine terminals.
