Circuit Breakers, Switchgear & Power Transformers

Introduction

This training course focuses mainly on the installation, operation and maintenance of high voltage switchgear and equipment, regarding auxiliary equipment necessary for its operation. High voltage equipment plays a vital role in the safe distribution of electrical power. The equipment needs to be operated in a safe manner securing continuity of supply to consumers. Technical aspects of switching devices, as well as their maintenance requirements, are briefly included in this training course to understand the risks associated with switchgear operation. Aspects of modern maintenance techniques in asset management will be covered at the level appropriate for this training course. Protection systems are installed to prevent faults from damaging electrical plant and to initiate isolation of faulted sections in order to maintain continuity of supply elsewhere on the system. Also, this training course will explore important aspects of power transformers. 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 with increasing demand in electrical power and reduction of carbon footprint, new innovative and intelligent transformers have emerged. With the digitalization of substation operations, electrical power transmission and distribution has been more efficient. The design and operation of any transformer must fulfil specific requirements 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 training course will highlight:

  • The roles of MV and HV switchgears
  • Compression principles of circuit breakers
  • Application and installation of vacuum interrupters
  • Importance of maintenance and testing
  • Selection of oil-filled and dry-type transformers
  • Ester based oil for new transformers
  • Basics of smart digital transformers
  • Maintenance and commissioning procedures
  • Testing, diagnostics and monitoring technologies
  • Protective relays and characteristics
