About the course

As utilities reassess equipment to upgrade existing infrastructures or build new ones, Power Engineering is undergoing significant change. There is a need to train engineers in the fundamentals of High Voltage (HV) technology, equipment, and laboratory test techniques. This course covers HV test and measuring systems, as well as analysis techniques applied to power system apparatus such as cables, insulators, transformers and generators. Hands-on lab work is done in the Kinectrics High Voltage Lab, which is equipped with AC impulse and DC test equipment. The HV Lab is used on a regular basis by national and international utilities for measuring and testing.

Course Objectives
