Compact substations require integrated and space-saving protection solutions that can handle transformer, feeder and often arc flash functions. They need rugged, maintenance-friendly relays capable of operating in constrained environments.
With its depth of only 90mm including terminal plugs, the SYMAP®Compact(+) product series is the ideal solution for limited space cabinets. With the long list of standard protection functions included in a single device, along with powerful integrated PLC functionality for customized logic, it is a versatile device which can cover multiple applications and protected elements.
Substations often require a control bay unit which SYMAP®Compact(+) can cover as a combined protection and control device, supporting:
- control of up to 8 switching elements (breakers, disconnectors, earthing switches)
- bay interlocking logic
- single-line diagrams and other programmable user pages on touchscreen HMI
- time synchronization: SNTP, PTP, IRIG-B
- SCADA integration via IEC 61850 (ED1 and ED2), IEC 60870-5-103/104, Modbus RTU/TCP, Profibus DP and fast substation level GOOSE communication
Communication redundancy options include RSTP, PRP, HSR, ensuring high availability in substation networks.
For projects requiring a larger number of signals, using the modular EBS extension board system with SYMAP®Compact(+), users can benefit from:
- up to 50 additional binary inputs
- up to 24 additional binary outputs
- multi-voltage input compatibility (12–230 V AC/DC)
The modularity enables scalable substation automation.
