High Voltage Switching Safety , Operations and Maintenance

INTRODUCTION:

This High Voltage Switching Safety, Operations and Maintenance training course will feature the importance and relevance of switching in High Voltage Power Systems in operation and maintenance. Engineers and technicians will familiarize themselves with relevant safety procedures and practices used for its implementation. General guidance to safety and practical examples of Management Systems will be presented as well as necessity of having procedures during operation and maintenance.

Technical aspects of switching devices as well as their maintenance requirements are briefly included in the course in order to understand the risks associated with switchgear operation. Aspects of modern maintenance techniques in asset managements will be covered at the level appropriate for this training course.

In addition to the procedures for safe switching the course will provide examples of incidents following misconducts or equipment failure. Investigation procedures for such incidents will be discussed following the internal actions and fulfilling the legislative aspect.

This training course will highlight:

  • Standards guides and codes of practice
  • General guidance to work safely
  • Safe switching (operation) of the switchgear
  • Importance of earthing
  • Site safety management
  • Investigation procedures
  • Legislative aspects

OBJECTIVES :

At the end of this training course, you will learn to:

  • Understand what are the hazards associated with switching
  • Correctly select and use of equipment
  • Managers and supervisors will learn the actions in respect to safety
  • Learn how to assess safe working practices
  • Discuss network operator’s procedures
  • Discuss and understand set of distribution safety rules through examples

WHO SHOULD ATTEND:

Managers at decision-making positions should also be aware of legal obligations if not complying with procedures and code of practice.

  • Operational staff and managers working in industrial and distribution systems
  • Maintenance engineers and technicians
  • Site managers, site engineers and senior technicians working in electrical utility companies and industrial organizations
