REM543BM215AAAB Machine Terminals

• Integrated machine terminals for the protection, control, measurement and supervision of small and medium size generators, synchronous motors and large asynchronous motors.
• Voltage and current measurement via conventional measuring transformers or current sensors and voltage dividers.
• Fixed man-machine interface including a large graphic display, or an external display module for flexible swichgear installation.
• Extended functionality including protection, control, measurement, condition monitoring and communication.
• Non-directional/directional overcurrent/earth-fault protection functions, over- /undervoltage protection functions and special functions for the protection of motors and generators, e.g. voltage controlled overcurrent protection, differential protection with several principles, underexcitation protection, underimpedance protection (line back-up prot.), thermal overload protection, protection against unbalanced load, abnormal frequency protection, reverse or low-forward power protection and start-up supervision for motors.

• Control functions including local and remote control of switching objects with synchro-check, status indication of the switching objects and interlockings on bay and station level.
• Measurement of phase currents, phase-tophase and phase-to-neutral voltages, neutral current and residual voltage, frequency, power factor, active and reactive power and energy.
• Optional RTD/mA I/O-module for stator winding, bearing and ambient temperature monitoring. Analog mA outputs for interfacing with process control system.
• Condition monitoring including circuitbreaker condition monitoring, trip circuit supervision and internal self-supervision of the machine terminal.
• Communication over three communication interfaces: one for local communication with a PC and the others for remote communication with a substation control system or with a substation monitoring system.
• Part of the ABB’s Distribution Automation system
