Description

Circuit breakers are an essential element in a power system network in maintaining the continuity of power supply and power quality to the industrial and commercial consumers. The Circuit breaker comprises of switching mechanism and must operate safely under all conditions to connect and disconnect circuits

This course will cover all aspects of high and medium voltage circuit breakers and their use in substations , general design considerations, application of switching and power equipment, fault withstand and interrupting capabilities, interface with  protection/control, automation and communication, and maintenance considerations.

Objectives

To provide a practical understanding of  design, application and maintenance aspects of high and medium voltage circuit breakers for utility networks and industrial plants.

Who Should Attend

Electrical power systems engineers in utilities and industrial plants, managers of private electricity producers and large power consumers, consulting engineers, manufacturers of power equipment, other engineers and technical personnel involved in the design, operation and maintenance of high/medium voltage substations.

Instructors: Ajit Bapat

The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
