A3 - Transmission and distribution equipment

Mission

To facilitate and promote the progress of engineering and the international exchange of information and knowledge in the field of high voltage equipment. To add value to this information and knowledge by means of synthesizing state-of-the-art practices and developing recommendations.

 

Technological field of activity

  • Devices for switching, interrupting, or limiting currents including circuit breakers, load switches, re-closers, ring-main units disconnectors, earthing switches and fault current limiters wherever installed.
  • Surge arresters, capacitors, busbar and equipment insulators, instrument transformers, bushings, and all other equipment within the substation not specifically covered under another equipment study committee’s scopes.

Scope

Within its technical field of activity, Study Committee A3 addresses topics throughout the asset management life-cycle phases; from conception, through research, development, design, production, deployment, operation, and end-of life. At all stages, technical, safety, economic, environmental and social aspects are addressed as well as interactions with, and integration into, the evolving power system and the environment. All aspects of performance, specification, testing and the application of testing techniques are within scope, with a specific focus on the impact of changing interactions and demands due to evolution of the power system. Life cycle assessment techniques, risk management techniques, education and training are also important aspects.


Within this framework additional specific areas of attention include:

  • Theory, principles and concepts, functionality, technological development, design, performance and application of materials, efficiency.
  • Manufacturing, quality assurance, application guidance, planning, routing and location, construction, erection, installation.
  • Reliability, availability, dependability, maintainability and maintenance, service, condition monitoring, diagnostics, restoration, repair, loading, upgrading, uprating.
  • Refurbishment, re-use/re-deployment, deterioration, dismantling, disposal.
