Overview
This course deals with the testing of distance, differential, negative sequence overcurrent, reclosing, sync check, and breaker failure. The course will start with the theory related to distance and differential functions followed by hands on testing.
Day 1
R-X Diagram
- Basic elements of an R-X diagram
- How do we use it to represent load, line impendence, etc.
- How do we use this diagram to observe distance relay behavior using this diagram?
Distance Protection
- Basic principles
- Characteristics & operating principles of Mho and Quad
- Polarization for phase and ground distance
- Determination of directionality
- Step distance protection using distance relays
- Infeed effect
- Impact of arc resistance
- K-factor used in ground distance
- Expanding Mho characteristics
- Zone 1 acceleration
Differential Protection
- Vector compression
- Amplitude compensation
- Handling various transformer connections
- Harmonic restraint
- Zero sequence elimination for external faults
Day 2
Testing of differential relays
Day 3
- Testing of Sync. Check function
- Testing of a Reclosing function of a microprocessor relay
- Testing of a Breaker Failure Function
- Testing of a Negative Sequence overcurrent function
A brief description of operating principles these relays will also be presented followed by hands on testing of these relays using Doble relay test sets. Both manual and automated testing using a test plan will be used for training. A combined application course coupled with hands-on training.
This course/training is intended for the following audience:
- Senior and Junior level technicians who are involved with testing of electro-mechanical/microprocessor relays
- Technicians who wish to enhance their knowledge of moderately complex relays
- Technicians who wish to learn how automated testing is performed to test moderately complex.
This class will be hosted at 2200 Gateway Center BLVD Suite 207 Morrisville, NC 27560
