Protective Relay Maintenance, Advanced | Hands-On Certification Training Course

4.5-Day | 3.6 CEUs | $1,885 | Hands-on | Course #140 | 8 am-4:30 pm (final day ends at noon) 

Course participants learn the basics of transmission line protection combined with hands-on, realistic training on actual relays. Laboratory exercises will cover proper relay maintenance, specific test procedures including proper calculations for impedance relay testing, and detailed adjustment and calibration procedures utilizing state of the art relay test sets. Participants will understand applicable NETA testing standards, what test result information should be recorded, and what hand tools are necessary for proper relay adjustment and calibration.

Learning Objectives

  • Understand how the relay is applied in the power system
  • Identify electromechanical relay components
  • Interpret AC and DC relay schemes
  • Perform as found/left tests and calibrate the subject relays (ANSI device numbers)
  • Explain the application of these relays
  • Utilize a relay test set to perform direct injection testing and evaluate results
    • Directional Distance Relays (21)
      • Mho
      • Reactance
  • Sync Check Relays (25)
  • Directional Overcurrent (67)
  • Ground Directional Overcurrent (67G)

The student should have basic knowledge of AC/DC electricity. In addition, students must bring a scientific calculator. Technicians that successfully complete this course will be certified to maintain electromechanical relays that protect utility lines and substation equipment. This certification is valid for 3 years from the date of issue.


This course is required for our Advanced Protective Relay Maintenance Technician Certification Program.
