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 and lab practice, the participant will demonstrate that he/she is able to:
• Outline how the relay is applied in the power system and identify critical components.
• Interpret external wiring connections and internal logic functions.
• Follow NETA standards when performing tasks with the microprocessor.
• Establish communication with the relay.
• Verify proper operation of relay indicators and output operation.
• Connect relay test set and perform metering check and field tests.
• Perform the following relay element tests and interpret the results:
- Percent Differential (pickup and slope)
- Instantaneous Differential
- Second Harmonic Restraint
- Phase Time Overcurrent
- Phase Instantaneous Overcurrent
- Phase Directional
- Ground Time Overcurrent
- Ground Instantaneous Overcurrent
- Restricted Ground Fault
- Neutral Time Overcurrent
- Neutral Instantaneous Overcurrent
- Phase Undervoltage
- Phase Overvoltage
- Neutral Overvoltage
- Volts per Hertz
Note: Relays used in lab exercises will be SEL-787, GE-URT60, and ABB RET615.
