HighPROTEC – Ready for the Future

HighPROTEC, the next generation of protection relays from SEG Electronics, makes protecting medium voltage feeders, generators, transformers, and motors simple, reducing effort and cost. It can be easily configured for specific application requirements and accepts 0‒800 VAC and 1A / 5A inputs, a wide range of supply power, communication protocols (DNP3.0, IEC 61850, IEC 60870-103, Modbus, Profibus), and menus in seven different languages. It displays system connections, operating values, and messages/alarms/fault data – making it easy to use. Worldwide certifications include CE, UL, CSA, EAC, and Marine certifications.

Easy to use (individual configurable devices with adaptable menu structure, plausibility check, ANSI menu structure can be turned on and off …
Reduces your maintenance and commissioning efforts (Integrated Fault Simulator,…)
Highest hardware flexibility (1A / 5A inputs, wide range power supply,...)
No hidden costs: Protection packages inclusive. The operating software Smart View can be downloaded and installed without extra charge.
8 selectable languages within the relay (English / German / Spanish / Russian / Polish / Portuguese / French / Romanian)
Various communication protocols (IEC 61850, Modbus, DNP3, Profibus, IEC 60870‑5‑103)
Worldwide certifications: CE, UL, CSA, EAC,...
Covers Worldwide interconnection standards: IEEE1547, BDEW, G99‑1‑3
