Power System Protection Applications and Performance Analysis

See upcoming dates

Course Overview

During this intensive course, you will learn the principles of power system protection leading to an understanding of overall system protection. The course instructors will supplement the lectures on protection practices with presentations of field oscillograms illustrating disturbances that trigger protective action and an analysis of the resulting responses.

Who Should Attend?

  • Electric utility engineers involved in applying, simulating, and testing protective relaying devices
  • Technicians, project managers, managers, and others involved in electric power systems and interfacing with relaying and substation communications and automation

Testimonials

"Charlie Henville is a pleasure to listen to. His presentations are very detailed yet clearly delivered and easy to follow."

"An excellent overview of the various protection schemes."

"I've been to UW–Madison's EPD courses twice. I think you offer the best professional development experience I can find. This includes topics, instructors, facilities, technology, meals, etc. Thanks for a great effort. You have thought about a lot of extras and details. Well done."

Instructors

John Bettler

John Bettler’s responsibilities include setting all distribution relays (line, bus & transformer), running fault or coordination studies and the field in troubleshooting. He was previously the Cogeneration relay engineer, and has also worked in marketing and on field engineering assignments. John is a registered PE in the state of Illinois and holds a MSEE from IIT and a BSEE from Iowa State.

Charles Henville

Charles Henville is a native of the island of St. Kitts in the West Indies. His early education was in Jamaica, and he later graduated from the University of Cambridge in England in 1969. He has also received a Master of Engineering degree from the University of British Columbia in 2000.

After a thirty-year career with BC Hydro in Canada, he retired in 2005 from the position of principal engineer in protection planning. Since 1977, he has been responsible for the application and setting of protection systems for generation, transmission and distribution equipment with voltages ranging from 600 V to 500 kV. He now runs his own consulting company in power system protection. Charles is well experienced in training engineers in power systems. In addition to teaching at the University of Wisconsin, he is adjunct faculty at Gonzaga University and the University of British Columbia, and has presented training courses to working engineers world wide. He is well recognized in the IEEE, being a Fellow grade member, a past chairman of the Power Systems Relaying Committee and a past distinguished lecturer of the Power and Energy Society.
