Course Description

Protective relays monitor circuit conditions and initiate protective action when an undesired condition is detected. When required to operate because of a faulted or undesirable condition, it is imperative that protective relays function correctly. This course covers all topics related to isolating faulted circuits or equipment from the remainder of the system so the system can continue to function, limiting damage to faulted equipment, minimizing the possibility of fire or damage to adjacent equipment, and minimizing hazards to personnel. 
 

Course Objectives

By the end of this course, the participant will be able to:

• Perform required electrical tests and adjustments on basic protective relays.
• Read relay schematics found in manufacturer instructional literature.
• Apply test connection diagrams in manufacturer instructional literature to participant’s specific relay test sets.
• Use timing characteristic curves for basic protective relays.
• Understand the operation of over current, voltage and differential protective relays.
• Understand the basic and complex generation relay theory, application and components.
• Interpret wiring diagrams.
• Perform visual and mechanical inspections.
• Use of MPRT with TVI.
• Test, calibrate, repair and troubleshoot the following relays in lab:
• Overcurrent (COV, IJCV).
• Negative sequence (COQ, SGC).
• Loss of field (KLF, CEH).
• Reverse power (CW, ICW).
• Differential (CA, CFD).

Who Can Benefit

• Technicians with relay testing experience or electrical control systems experience.
• Supervisors of engineers who are responsible for the relays testing and maintenance.
• R&D personnel and Power System Design Engineers.
