Principles of The Maintenance of Electrical Switchgear

Introduction

This training course will present a comprehensive capsule of all the knowledge essential for the medium voltage and high voltage switchgear operations and walk the participants through the switchgear design process using a set of interlinked case studies. The training course focuses mainly on the operation and maintenance of distribution equipment namely transformers, circuit breakers, contactors, isolators and dis connectors (this will also include the auxiliary peripherals and control circuits).
Medium and high voltages switchgears are the integral component of any electrical distribution system; hence, the selection and installation of these switchgears are vital so as to provide protection and safe distribution of electrical power. The equipment needs to be operated in a safe manner securing continuity of supply to consumers.
