Transformer Operational Principles, Selection & Troubleshooting

Code Date Venue Fees
EL009 24 - 28 Dec 2017 Dubai - UAE $4,500 Register

Introduction

Power and distribution transformers are among the most important and most expensive components of power systems, their failure can be very costly and dangerous for other major equipment and personnel alike besides imposing extraordinarily high costs on the electrical installation. The utilization of oil-filled and dry type transformers are increasingly visible due to their outstanding characteristics

The design and operation of any transformer must fulfill certain requirements in order to withstand the electric, thermal and mechanical stresses during its service life. Tests and maintenance of transformers according to the relevant standards are intended to ensure that a transformer passing them will give trouble-free service for many years under the conditions it is likely to experience after its installation.

This seminar will highlight:

  • Design and construction details
  • Selection methodology for dry type and oil-filled transformers
  • Maintenance and commissioning procedures
  • Troubleshooting checklists and failure analysis techniques
  • Testing, diagnostics and monitoring technologies

Objectives

At the end of this seminar, you will learn to:

  • Describe the various classifications and types of transformer
  • Appreciate the importance of transformer maintenance
  • Analyse the various transformer test results
  • Classify the transformer cooling methods
  • Recognise the merits of transformer designs

Training Methodology

Each seminar participant will receive a copy of the comprehensive seminar notes. The presenter will outline and discuss the topics using computer displays, videos and PowerPoint presentation. The seminar is designed to have an interactive format to maximize delegate participation. Questions and answers are encouraged throughout and at the daily sessions. Needs-Based case-studies and examples will be discussed in problem solving workshop sessions. This gives participants the opportunity to discuss with other delegates and the presenter their specific problems and appropriate solutions.

Organisational Impact

Upon completion of the seminar the organizational impact would be:

  • Technical training and up-skilling to improve and realise the full potential of a competent workforce
  • Productivity increase through minimisation of project time acceptance/design and testing
  • Identification for opportunities of improvements due to deep understanding of the presented state-of-the-art maintenance technologies
  • Networking of personnel with technology leaders and other engineers
  • Attitude change of workforce, as continuous follow up of new technologies and their up taking could otherwise create workforce with high resistance to change due to lack of understanding
  • Ensure safety practices are adhered when carrying out electrical installation activities

Personal Impact

On successful completion of this seminar delegates will be able to:

  • Understand the principles of operation and construction of the various types of  transformer
  • Identify the different components in the transformers
  • Appreciate the testing and maintenance procedures for transformers
  • Be familiar with construction of the transformer, transformer winding connections and cooling systems
  • Recognize the effects of transformer off-load and on-load tap changers
  • Comprehend site acceptance tests for newly installed transformers

Who Should Attend?

The technicians and maintenance staff will be able to comprehend the types, construction, operations, function of transformers. This will enable them to carry out effective maintenance activities

This seminar is suitable to a wide range of professionals but will greatly benefit:

  • Electrical engineers
  • Maintenance technicians
  • Electrical supervisors
  • Engineering professionals
  • Managers of the electrical engineering department
