Solid State Protective Relay Maintenance Technician

Solid State Protective Relay Maintenance Technician


Solid state relays perform all the same functions as electromechanical relays. But, because of their electronic circuitry and microprocessors, solid-state relays provide many functions not previously available. Generally, solid-state relays are smaller and more compact than their mechanical counterparts. The precision of electronic relays is greater than that of mechanical relays, which allows you to achieve a closer system coordination. Proper testing and maintenance ensures the integrity of the protection system periodically after installation. Calibration testing is required to verify relay setting calibrations, configurations, and to identify any protection system defects. Functional testing is required to verify that the intent of the protection system is being carried out. This certification program will qualify technicians to safely maintain basic and complex solid-state protective relays. What is certification? Certification means you have achieved certain performance criteria - knowledge, skills and abilities through training. Certifications prove your skills, and their value is the recognition of customers, coworkers and employers. This certification also meets the requirements of OSHA 29 CFR 1910.269(a)(2)(vii).


  • Basic and complex solid-state relay theory, application and components
  • Interpret internal and external wiring diagrams and timing curves
  • Perform visual and mechanical inspections
  • Test, calibrate, repair and troubleshoot the following relays: Directional overcurrent (BE1-67), Reverse power (BE1-32)


This certification requires completion of one course: Protective Relay Maintenance, Solid-State. This course is 4.5 days and 3.2 CEUs.
