Protective Relay Maintenance, Advanced (PRMA)

Protective Relay Maintenance, Advanced

COURSE OVERVIEW

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.

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.

LEARNING OBJECTIVES

The Protective Relay Maintenance Advanced Transmission course is an intensive, hands-on, lab oriented presentation covering:

  1. Impedance Relays (21)
    1. Mho
    2. Reactance
  2. Sync Check Relays (25)
  3. Ground Directional Overcurrent (67G)
Upon completion of this course, the participant should be able to:
  • Identify electromechanical relay components
  • Interpret AC and DC relay schemes
  • Perform as found/left tests and calibrate the following relays (ANSI device numbers):
    • Distance (21)
    • Sync Check (25)
    • Directional Overcurrent (67/67G)
    • Transformer Percentage Differential (87T)
    • Targets and Indicators
  • Explain the application of these relays
  • Utilize a relay test set to perform direct injection testing and evaluate results

REQUIREMENTS

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.
