Introduction

This training course discusses the practical troubleshooting of electrical equipment and control circuits. It helps to increase the knowledge and skills of delegates in improving equipment productivity whilst reducing maintenance costs. This training course focuses on the main issues of troubleshooting electrical equipment and control circuits of today to enable delegates to walk onto their facilities to troubleshoot and fix problems as quickly as possible. The delegates will be able to identify, prevent and fix common electrical equipment and control circuits. The delegates will be aware of practical issues that go beyond typical electrical theory and focus on providing them with the necessary toolbox of skills in solving electrical problems which normally faced at industrial fields

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.
