TAMCO High Voltage Switchgears

Introduction

The duty of a circuit breaker is to switch on and switch off, once or repeatedly several times different electrical circuits during normal as well as abnormal operating conditions. Circuit breakers and switchgears specification, operation, testing, and maintenance are essential for engineers and technicians. This course designed to provide the participants with technical knowledge, practical experience, and good skills in the field.

Objectives

    By the end of this course the participants will;

    • Understand the arc phenomena and circuit interruption.
    • Know the different types of circuit breakers and industrial switchgears.
    • Be able to select circuit breaker specification.
    • Know the maintenance procedures.
    • Be able to do all tests on circuit breakers.
    • Be able to detect circuit breakers troubleshooting.
    • Be able to use circuit breaker curves and make protection coordination

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies, and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations. The online course is conducted online using MS-Teams/ClickMeeting.

Who Should Attend?

The course is designed to electrical engineers and highly qualified technicians concerned with circuit breakers and switchgears in electrical utilities, electrical distribution, and transmission.
