In its 30-plus year lifespan, a protective relay may only need to operate for a fraction of a second. But when it’s needed, it has to perform. Servicing protective relays per manufacturer and NETA recommendations ensures they work properly to prevent injury or extensive damage to your plant during an electrical distribution abnormality.


  • Relay startup and commissioning ensures proper protection for your system through inspection and testing
  • Maintenance and testing, based on the recommendations from NETA, NERC and NFPA, ensures your protection scheme continues to provide satisfactory performance for many years after installation
  • Compliance support such as asset management, testing, and reporting helps ensure your compliance with NFPA and NERC requirements
  • Qualified resources have the expertise to work in a variety of environments, as well as on a diverse installed base of devices with different operating practices


  • Greater reliability from your protective relays is achieved when functionality is checked through regular maintenance and testing
  • Fewer service disruptions that lead to substantial financial loss is due to the ongoing detection and correction of performance problems
  • More cost-effective maintenance is possible when relay testing is part of a proactive maintenance program rather than part of an emergency reaction
  • Better protection for people, equipment, and the bulk electric system is achieved by adhering to maintenance requirements
  • Easier reporting for regulatory compliance occurs due to documentation provided following relay maintenance and testing
