Electromechanical protective relays are commonly used to protect lines and substation equipment against overloads, faults and abnormal conditions.

NETA and FERC Maintenance and Testing Standards recommend testing relays at regular intervals based on equipment condition and reliability requirements. Through proper testing and maintenance, technicians can help insure the integrity of the protection systems, minimize damage to equipment and help insure service continuity. The Protective Relay Maintenance Advanced Transmission course is an intensive, hands-on, lab oriented class covering:
1. Impedance Relays (21)
a. Mho
b. Reactance
2. Sync Check Relays (25)
3. Ground Directional Overcurrent (67G)
The participant will 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 testing, and detailed adjustment and calibration procedures utilizing state of the art relay test sets. Participants will understand applicable testing standards, what test result information should be recorded, and what hand tools are necessary for proper relay adjustment and calibration.

Who Should Attend
This hands-on course is intended for electricians, technicians and engineers responsible for testing, maintenance and calibration of electromechanical protective relays that protect utility transmission lines and substation equipment. The participant should have basic knowledge of AC/DC electricity and basic relay testing experience.
