- Course 406.
- 1 Week.
- 3.6 CEU.
Participants will learn the basics of generator protection combined with hands-on training using actual relays. Laboratory exercises will cover proper relay maintenance, specific test procedures,
and detailed adjustment and calibration procedures utilizing state of the art relay test sets. Participants learn the applicable NETA testing standards, what test result information should be recorded and what hand tools are necessary for proper relay adjustment and calibration.
Understanding proper relay maintenance procedures will ensure that the generator and prime mover is protected from damage and are operating within prescribed boundaries. This course provides the understanding of generator protective zones and their associated protective relays.
The Protective Relay Maintenance Generation course is an intensive, hands-on, lab oriented presentation covering:
The course will be covering:
• Identify generator relay components and understand their operation.
• Interpret AC and DC internal and external drawings and schematics for the relay.
• Understand relay settings and calculate test parameters based on those settings.
• Know how to connect a relay test set to the relay to properly perform necessary tests.
• Perform standard field tests and properly calibrate components that are out of tolerance.
• Properly record and evaluate test results.
• Voltage controlled and voltage restrained overcurrent (27/51).
• Reverse Power (32).
• Loss of Field or Loss of Excitation (40).
• Negative Sequence (46).
• Generator Differential (87G).
Who Should Attend
This course is developed to challenge test technicians who want to thoroughly understand generator and unit protection and the testing, calibration, and maintenance of generator protective relays. Participants should have basic knowledge of AC/DC electricity and basic generator functions. Those technicians who qualify will be certified to test, maintain and calibrate the relays presented in the labs.
