COURSE OVERVIEW

This hands-on course is designed for test technicians and other persons involved in setting, testing and diagnosing microprocessor-based relays that protect generators, generator buses and transformers. NETA and NFPA 70B maintenance and testing standards recommend testing relays either every 2 years or at other regular intervals based on equipment condition and reliability requirements.

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 generators, generator buses and transformers.

LEARNING OBJECTIVES

Upon completion of this course, the participant should be able to:

  • Determine relay baud rate and other communications parameters.
  • Use manufacturers software to communicate with the relay.
  • Know what equipment is necessary to communicate with the relay.
  • Properly connect relay test equipment to the relay terminals by using connection diagrams and system schematics.
  • Know relay protective elements and how they work.
  • Know what metering and test functions to perform.
  • Read, Save and evaluate relay settings.
  • Read, Save, and evaluate event records.
  • Perform the following relay element tests and interpret the results
    • Backup Impedance (21)
    • Over excitation (24)
    • Reverse Power (32)
    • Loss of Excitation (40)
    • Negative Sequence (46)
    • Voltage Controlled Overcurrent (51C)
    • Voltage Restrained Overcurrent (51V)
    • Under/Overvoltage (27/59)
    • Stator Ground (64)
    • Frequency (81)
    • Generator Differential Elements (87)
  • Send original settings to relay after testing.

REQUIREMENTS

Participants should have a basic knowledge of AC/DC electrical principles as well as some knowledge of generator operation and generating systems.
 
Participants must bring a laptop that has Windows XP/Vista/7/8, 600+ MHz processor, 4+GB hard drive space, 1+GB RAM, a CD-ROM drive. iPads and tablets without CD-ROM or USB ports are not acceptable. NOTE: Administrative rights to install software must be granted for successful course completion.
