Electric Distribution Overvoltage Protection
Lee
Layton, P.E.
Overview
This
5-hour course reviews overvoltage situations on electric utility distribution
systems and the primary methods to protect the utility system from overvoltages.
The principle cause of overvoltages on an electric distribution system is
lightning surges. Lightning surges are covered in detail as well as the design
and operation of surge arresters. Protection methods including shielding, surge
arrester application, and structure design are discussed. The importance of
grounding to proper overvoltage protection is also reviewed.
The student must take a multiple-choice quiz consisting of
twenty-eight (28) questions at the end of
this course to obtain PDH credits.
