HighPROTEC protection and control devices

    Woodward HighPROTEC Power Protection Relays

    HighPROTEC represents Woodward’s latest generation of power protection relays with dual core processors. The new device line is designed for complete protection of power generating and distribution systems.

    During the development of the HighPROTEC Line, Woodward gives special emphasis to high flexibility and simple handling of the devices.

    All HighPROTEC relays are furnished with a high-contrast graphic display. Ongoing measuring values, messages, alarms, and fault data are displayed in clear text. Guiding text assists the operator when setting parameters. Inadmissible inputs are prevented by plausibility checks.

    All current and earth current inputs are designed for 1A and 5A. The nominal voltage of the voltage inputs and the switching thresholds of the digital inputs can be adjusted via software. The wide-range power supply unit covers all standard auxiliary voltages, both for DC and AC.
