Relay Upgrades & Replacements

Relays can be seamlessly upgraded or replaced adding reliability, functionality, and communication capabilities. Many facilities are replacing their aging relays with microprocessor-based relays, for optimal protection. Relay retrofits and upgrades provide a cost-effective way to leverage the advantages of microprocessor relays, without the expense of installing new switchgear. ERS is experienced with all major manufacturers and relay applications, and our services include engineering evaluation, relay logic design, integration, and settings, panel fabrication, demolition, installation, testing, and startup.

Circuit Breaker Upgrades and Replacements

Circuit breakers play a critical role in protecting the people and equipment in your facility, and are integral in limiting the damage should a fault occur. But like all electrical components, circuit breakers can wear out and require an upgrade or replacement. By replacing your aging circuit breakers, you will lower your maintenance requirements and reduce the safety risk to your personnel. Services include circuit breaker testing and replacement.

NERC Compliance

Ensure regulatory compliance with North American Electric Reliability Corporation (NERC) requirements and avoid costly fines. This takes knowledge of the ever-changing and complex regulations. These regulations require utilities and power generation and transmission facilities to implement an ongoing, systematic program to test, maintain, and document the performance of protection scheme devices that impact the Bulk Electric System (BES). Services include NERC engineering evaluation and compliance assessment, and relay settings and logic programming.


  • Enhanced system protection is achieved when engineers design a retrofit solution tailored to your system
  • Improved functionality and control happens as new relays utilize the latest technology and advanced communication capabilities
  • Reduced maintenance or operating costs is possible as newer equipment with advanced technology streamlines maintenance and allows for more efficient operation
  • Better system insight for data-driven decision making is possible as the built-in protocols of microprocessor relays make data available anywhere on your system
  • Extended life of equipment occurs as circuit breakers are properly maintained and work to limit equipment damage during a fault
  • Improved reliability and mean time between failures (MTBF) results from having proper relay settings and a protection scheme that is expertly engineered
  • Simplified calibration and extended intervals between testing lead to lower overall maintenance costs
  • Simplified regulatory compliance is possible due to self-testing features that streamline or simplify required testing and reporting
