ABB REC670 Interval measurement, control and protection device

. Can be used in a variety of busbar wiring methods

-Can be used for control and protection with up to 6 feeder intervals.

. Control of up to 30 controllable devices .

. Typical type-tested electrical interlocks for single breaker, double breaker, one and a half breaker configurations .

. High impedance differential protection for T-wiring or busbar systems .

. Directional power protection

-Power reversal, positive phase low power, excess active and reactive power protection .

-With phase angle compensation

-Two-stage exit (alarm/trip) .

. Synchronisation, simultaneous detection and no-voltage checking functions for single or multiple circuit breakers: .

-Selectable charging direction

-Two function blocks with built-in simultaneous voltage selection

-Automatic or manual synchronisation and simultaneous checking with different setting values.

-Settable breaker closing time (simultaneous function).

. Single-phase/two-phase/three-phase automatic reclosing function: two function blocks with priority circuits for multi-breaker wiring.

-With synchronisation and simultaneous detection function

-Function can be activated or deactivated via remote communication or local switching inputs.

-Optional additional functions such as circuit breaker failure protection, voltage protection, thermal overload protection, control and monitoring.

.IEC61850-8-1 station level bus data communication

. Station Bus Data Communication Module IEC60870-5103.TCP/IP or EIA-485 DNP3.0.LON and SPA

.C37.94 Remote communication modules

-Contains 192 switching signals

-Short, medium and long distance fibre optic modems

-G.703 and G.703E1 external MODEM (short distance fibre optic MODEM support, mounted on communication bracket) .

. Integrated fault recording and event logging (40 analogue signals, 96 switching signals) .

. Energy metering and demand processing functions

-The output values of the measuring module (MMXU) can be used to calculate the electrical energy and the maximum electrical energy demand. Active and reactive power are calculated at the inlet and outlet, respectively, and the values can be read or generated in the form of pulses.
