Training Certificate

Prolific Consultants FZE Certificate of Course Completion will be issued to all attendees.

Course 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.

Course Objective

Participants attending this program will be able to:

• Diagnose electrical problems
• Eliminate the expensive trial and error approach
• Reduce unexpected downtime on electrical motors and other equipment
• Improve plant safety
• Learn specific techniques to troubleshoot equipment and control circuits
• Analyze Equipment problems
• Determine causes of equipment failure

Suitable For

• Electrical engineers
• Junior Electrical engineers

Training Methodology

A highly interactive combination of lecture and discussion sessions will be managed to maximize the amount and quality of information, knowledge and experience transfer. The sessions will start by raising the most relevant questions, and motivate everybody finding the right answers. The attendants will also be encouraged to raise more of their own questions and to share developing the right answers using their own analysis and experience.

All presentations are made in excellent colorful power point. Very useful Course Materials will be given.
