Modular and flexible architecture

· Multiple modes of installation

– Centralized layout:

Installation of bay units and central unit in one or several cubicles

– Distributed layout:

Bay units distributed with short connections to CTs,isolators, circuit breakers, etc.

· Interference-proof connections between bay units and central unit by fiber-optic cables (max. 2000m)

· Replacement of existing busbar protection schemes without restrictions e.g. in case of substation extensions

· Easily extensible

· Only one hardware version for

– Settable 1A and 5A rated current inputs

– Nominal frequencies of 50Hz and 60Hz

· Minimum number of spare parts needed due to standardization and low number of varying units

Seamless substation automation integration

· User-friendly, PC-based interface (HMI)

· Operator integration into PCM600 for readout of configuration, events and disturbance records.

· Communication with substation monitoring and control system

– via IEC 61850-8-1 Edition 1 or Edition 2

– via IEC 60870-5-103

· Local HMI with comprehensive system information on every unit

· Fully numerical signal processing

· Comprehensive self-supervision

· Integrated event recording

· Integrated disturbance recording for power system currents and voltages

· Optional redundant power supply for central units

Cyber security

· Secure communication

· User Access Management

· User Activity Logging

· Centralized account management

· Verified robustness

Additional options

· Breaker failure protection
