Generation and Measurements of High Voltage and Overhead Transmission Line Insulators

Course Description

You will learn everything about high voltage insulator functions, how breakdown occurs and testing high voltage circuits in lab. The course covers the concept and operation of HV testing transformer, cascaded and resonant HV transformers, TESLA coil, etc. After taking the course, you will have a clear picture of the main features of overhead line insulators, how to avoid flashover of the insulator, different tests to be made on the insulator and corona/sparkover effect in power engineering.

The course consists of 49 lessons and 5h 1m total length. Downloadable materials (PDF) are included.
