Cost Effective Strategies for the Maintenance of Electrical Power Systems

Cost Effective Strategies for the Maintenance of Electrical Power Systems

Introduction

Electrical equipment is an expensive investment for the electrical industry. The equipment needs to be operated safely to achieve a maximum return on the initial investment.

This requires the equipment to be:

  • Maintained in a safe manner
  • Operated within an effective management system

The training seminar focuses mainly on maintaining electrical equipment for a cost effective solution.

The training seminar is split into two modules:

MODULE I – Troubleshooting and Maintenance of Electrical Equipment

MODULE II – Fault Finding Techniques on an Electrical Power System

Each module is structured and can be taken as a stand-alone training course; however, delegates will maximise their benefits by taking Module 1 and 2 back-to-back as a two-weeks training course.

Objectives

This training seminar is designed to increase the troubleshooting and fault finding diagnostic skills of engineering teams of a modern power system.

Training Methodology

The goals of each participant are discussed to ensure their needs are fulfilled, as far as possible. Questions are encouraged throughout, particularly at the daily wrap up sessions. This provides opportunities for participants to discuss specific issues and, if possible, find appropriate solutions. General discussions are employed to highlight particular points and to illustrate particular conditions.

Organisational Impact

The training seminar will allow delegates to interact and gain shared experiences of others along with:

  • An understanding for the need for routine inspection and maintenance
  • Troubleshooting techniques on various pieces of electrical equipment
  • Safe working practices being stressed and observed
  • Risk reduction methods investigated

Personal Impact

On successful completion of this training seminar, delegates will understand:

  • The need for routine inspection, adequate maintenance of equipment and accurate record keeping
  • Methods of maintenance management, using safe systems of work
  • How to co-ordinate maintenance activities for best utilisation of time and resources, while ensuring safety is not compromised
  • Switchgear maintenance requirements and troubleshooting techniques.
  • Transformer maintenance requirements and troubleshooting techniques
  • Cable installation and troubleshooting techniques
  • The use of non-intrusive condition monitoring methods

Who Should Attend?

  • Electrical Professionals
  • Electrical Engineers
  • Electrical Supervisors
  • Technicians
  • Professionals responsible for the operation and maintenance techniques
