AVO - Protective Relay Maintenance, Advanced

PROTECTIVE RELAY MAINTENANCE, ADVANCED | (PRMA | #14OA) 4.5 DAYS | 3.2 CEUs

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.

To receive 3.2 CEUs, participants must attend 4.5 days of class (32 contact hours) and attain a minimum average grade of 80% (overall grade will consist of 50% lab practice and 50% final exam). Upon completion of this course the partici-pant will demonstrate that he/she is able to:

• Identify electromechanical relay components.
• Explain the application of the relays.
• Interpret AC and DC relay schemes.

• Perform as found/as left tests and calibrate the following relays (ANSI device numbers):

  - Distance (21)

  - Phase Directional Overcurrent (67)

  - Ground Directional Overcurrent (67G)

  - Targets and Indicators

• Perform direct injection testing and evaluate results.
