Overview

Essential details：REM543CG214AAAA REM543 Machine Terminals

DESCRIPTION

The REM 543 and REM 545 rotating machine terminals are designed to be used as an integrated main protection system of generator and generator-transformer units in small and medium-power diesel, hydroelectric and steam power plants, etc. The protection of large and/or important MV synchronous and asynchronous motors used e.g. in pumps, fans, mills and crushers during start-up and normal run forms another application area. The REM 54_ machine terminals as integrated packages make possible compact marine environment solutions for unit protection, too. In addition to protection, measurement, control and condition monitoring and general functions, the machine terminals are provided with a large amount of PLC functions allowing several automation and sequence logic functions needed for substation automation to be integrated into one unit. The data communication properties include SPA bus, LON bus or MODBUS communication with higher-level equipment. Further, LON interbay communication, together with PLC functions, minimizes the need for hardwiring between the machine terminals.

Product parameter

The machine terminals REM 543 and REM 545 differ from each other in the number of digital inputs and outputs available. Please refer to the section “Ordering” for more details.
The REM 54_ machine terminals incorporate
a wide range of functions:
• Protection functions
• Measurement functions
• Control functions
• Condition monitoring functions
• General functions
• Communication functions
• Standard functions
The function blocks are documented on the CD-ROM “Technical Descriptions of Functions” (1MRS 750889-MCD).

APPLICATION

Protection is one of the most important functions of the REM 54_ machine terminal. The protection function blocks are independent of each other and have their own setting groups, data recording, etc. Typical current-based protection functions (e.g. overcurrent) can use either Rogowski coil or conventional current transformer measurement. Correspondingly, voltage-based functions (e.g. overvoltage) use either voltage dividers or voltage transformers. For further information about functionality levels and the protection functions included in them, refer to the table “Functionality levels, protection functions” in section “Ordering”.
