Overvoltage protection

Learn how to economically prevent excessive transient overvoltages from damaging electric utility distribution systems equipment or interrupting normal power system operation. Problems allow students to explore standard, as well as extraordinary conditions where standard overvoltage protection schemes may not be effective.

Target audience

The workshop is designed for utility distribution engineers or any engineer who is involved with design or implementation of overvoltage protection schemes for utility distribution systems.

Learning objective

The goal of this course is to explain how various overvoltage protection schemes are designed and to instruct how to solve practical and realistic overvoltage problems.
