Course Overview

This 3-Day Course will focus on design of transmission and distribution protection schemes utilizing advanced and highly reliable technology. This will include fundamentals on protection, relay design and protection schemes for transmission lines, transformers and bus. Additionally the course will focus on settings of feeder and transformer protection schemes, and selection of current and voltage instrument transformers for those protection schemes.

Issues surrounding power quality and their effect on power systems will also be addressed. This will include measurement and modelling techniques to identify power quality problems and mitigating techniques.  Impact of electrical overstress on the design and operation of power systems and electronic equipment will be discussed and protection systems will be modeled to eliminate equipment malfunction and damage due to electrical overstress.
