This is a 3 and 1/2 day course.
Course Base Fees: $2,400 USD
PROT 411 provides an in-depth study of the methods used in designing protection for high-voltage power transformer protection and substation bus protection.
Engineers who need a comprehensive understanding of the design concepts and methods used in protecting high-voltage electrical substation bus and power transformers would benefit from this course.
- Overview of Power System Faults
- Relaying Fundamentals
- Instrument Transformers
(includes a class exercise)
- Overcurrent Protection Principles (includes a class exercise)
- Differential Protection Principle
- Bus Protection (includes a class exercise)
- Transformer Differential Protection
- Transformer Protection Exercise
- Transformer Nondifferential Protection
- Transformer Overcurrent Protection Exercise
- Substation Trip Circuits and Breaker Failure
Note: This course teaches fundamental knowledge but does not provide hands-on experience with SEL relays.
At the conclusion of this course, students can:
- Describe the protection requirements of power transformers and buses.
- Specify current transformers for protective relay applications.
- Define transformer protection issues and identify solutions using digital relays.
- Define bus protection problems and identify solutions for digital relays.
- Calculate relay settings for transformer and bus protection relays.
