WHO SHOULD ATTEND

This hands-on course is designed for test technicians and other persons involved in setting, testing, and diagnosing microprocessor-based relays that protect transformers. 

LEARNING OBJECTIVES

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 

          - Underfrequency 

          - Overfrequency 

          - Synchrocheck

Note: Relays used in lab exercises will be SEL-787, GE-URT60, and ABB RET615.

PREREQUISITES

Student must bring a laptop and have full administration rights to install software, to complete the class labs. Laptop must have Windows 7 or greater OS. 

Upon enrollment confirmation, an email containing instructions to install required software will be sent to the participant prior to attending the course. Please make sure you install the required software before attending the class.

REQUIREMENTS

AVO Training Institute is committed to the personal safety of each participant and require long pants and ANSI rated “safety-toe” work shoes for lab activities. Lecture courses may involve a tour of a work or shop area and for this reason open-toe shoes and shorts are not considered appropriate attire for the classroom.
