Microprocessor-Based relays are now an integral part of many power distribution systems. This hands-on course is designed for test technicians and other persons involved in setting,
testing, and diagnosing microprocessor-based relays that protect distribution feeders and buses.
The course will be covering:
• Determine relay baud rate and other communications parameters.
• Use manufacturer’s 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.
• Instantaneous and Time Overcurrent: Positive Sequence (50/51P Residual.
• (50/51N), Zero Sequence (50/51G), Negative Sequence (50/51Q).
• Under and Overvoltage (27/59).
• Frequency (81).
• Transformer Differential Elements (87).
• Send original settings to relay after testing.
Class participants will perform the following:
• Understand and use manufacturers proprietary setting software.
• Communicate with the relay.
• Upload and download relay settings.
• Read, interpret, and retrieve event reports.
• Read metering data.
• Test individual protective elements for proper operation using a protective.
• relay test set.
•Prove logic inputs and outputs.
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 distribution feeders and buses. Course participants should have a basic knowledge of AC/DC electrical principles as well as some experience with protective devices.
