Protective Relay Testing, Programming & Upgrades

Precision Protection for Your Power System

Protective relays are the first line of defense in any electrical power system. Their primary role is to detect system disturbances and initiate circuit isolation by activating the appropriate interrupting devices. In short, properly functioning relays and control schemes are critical to the safety, reliability, and performance of your electrical distribution system.

Smarter Protection with Modern Relay Technology

Relay technology has evolved rapidly in recent years. Today’s microprocessor-based relays offer greater sensitivity, flexibility, and functionality, often replacing entire banks of older electromechanical relays with a single device. These intelligent relays provide:

  • Enhanced fault detection and system diagnostics
  • Faster response times and event reporting
  • Reduced panel space and wiring
  • Lower long-term maintenance costs
