Protection Relays & Monitoring

At Alberta Governor, we provide protection relays and monitoring devices to provide protection from low and high frequencies, voltage, and other potentially hazardous activity. We can provide multi-function relays for specific, customized protection.

We carry the following protection relays and monitoring devices:

Woodward HighPROTEC Line

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. The HighPROTEC Line is developed for 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.

Woodward MFR 15

Woodward’s MFR 15 Series multifunction relays offer a comprehensive package of industrial-grade protection and basic power management features. This device was designed for generators and switchgear equipment that require independent protection, whether in isolated operation or in parallel with the utility source.

Features include:

  • Complete generator protection and controller in one unit
    * True RMS sensing Synchronization for one breaker
  • Load sharing
  • Discrete inputs for remote control
  • Programmable relay outputs
  • PC and front panel configurable
  • Microprocessor technology for accurate, repeatable and reliable operation
  • Programmable threshold set-points with individual time delays
  • CE marked
  • UL/cUL Listed
  • GL Approval

Woodward MFR 3

The MFR 3 Series multifunction relays offer a comprehensive package of industrial grade protection and power management features. These devices were designed for generators and switchgear equipment that require independent protection, whether in isolated operation or in parallel with the utility. Closed PID control loops, by analog or discrete bias outputs, offer control of voltage, frequency, active and reactive power.

Features include:

  • Complete controller with generator and mains protection, synchronizer, and load/var control in one single digital relay
  • True RMS sensing
  • Synchronization for one/two circuit breakers
  • Load/var sharing for up to 14 participants
  • Counters for kWh, kvarh, engine starts, operating hours, maintenance call
  • Freely configurable discrete and analog alarm inputs
  • Freely configurable relay and analog outputs
  • PC and front panel configurable
  • CAN bus based communication
  • Microprocessor technology for accurate, repeatable and reliable operation
    * Programmable two step threshold set points with individual time delays
  • CE marked
  • UL/cUL Listed

Woodward MFR 13

The MFR 13 model is a complete generator protection unit packaged into one compact device. Typical applications are generators and switchgear equipment that require independent protection architecture. Different packages offer additional functionality.

The MFR 13/GP is for generator protection use while the MFR 13/GPX adds synch-check functionality for one breaker. A MOD bus RTU Slave interface for communication is added for the MFR 13/GPX-I package.

Features include:

  • Complete generator protection in one unit
  • True RMS sensing
  • Synch-check
  • Discrete inputs for enabling and remote control
  • Programmable relay outputs
  • PC and front panel configurable
  • Microprocessor technology for accurate, repeatable and reliable operation
  • Programmable threshold set-points with individual time delays
  • CE marked
  • UL/cUL Listed
  • GL Approval
