Introduction

The continuity of Electrical Power Supply is very important to the consumers especially for industrial sector, where curtail of electrical power supply is costly.

Electrical systems are subjected to several external & internal influences like weather conditions, lightning phenomenon, pollution, insulation failure, temperature rise, etc., these influences cause abnormal operational condition, which could lead to voltage and frequency variations and feeder trips, brown out or black out of electrical system, and sometimes, may lead to equipment damage or system failure.

Performance and characteristics of electrical system configurations are vital factor in reducing or increasing the effect of faults on the system as earthling system, switch gear, protective relays, active and reactive power generation, etc.

This course discusses electrical system faults and elements of the system that affect its behavior during the fault. The cause also will suggest measures to mitigate the problems that would arise.

Many utilities need this course which studies the influences of the above-mentioned events on the electrical networks and their effect on the continuity of electrical power supply and how mitigate these problems.

Objective

By the end of the course participants will be able to:

Audience

This course is intended for Engineers & supervisors who work in transmission, distribution, maintenance, operation, control and analysis of Utilities & Industrial Electrical Networks.

Certificate

MAESTRO CONSULTANTS Certificate of Completion for delegates who attend and complete the training course

Methodology

Our courses are highly interactive, typically taking a case study approach that we have found to be an effective method of fostering discussions and transferring knowledge. Participants will learn by active participation during the program through the use of individual exercises, questionnaires, team exercises, training videos and discussions of “real life” issues in their organizations.
The material has been designed to enable delegates to apply all of the material with immediate effect back in the workplace.
