For generation protective relays to work efficiently and properly protect electrical equipment they need periodic maintenance. Regular inspection and maintenance of relays is paramount in protecting electrical systems from unscheduled outages. A number of problems can occur without proper maintenance. Relays will nuisance trip when set too low. If not coordinated, the wrong relay may trip and bring down large portion of the system. Other factors include changes in load, replacement of equipment, dust or dirt from the environment or age. Proper maintenance, calibration and testing of generation relays, including voltage controlled overcurrent, negative sequence, loss of field, reverse power and differential relays is essential to power system protection.

Learning Objectives
•Basic and complex generation relay theory, application and components

•Interpret internal and external 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 Should Attend
Designed for technicians, engineers, and supervisors that are responsible for the application, maintenance, testing and calibration of generation relays at power plants.

Requirements
Requires basic relay experience. Bring a scientific calculator.
