A3 High Voltage Equipment


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 synthesising state of the art practices and developing recommendations.


Responsible for the theory, design, construction, and application of high voltage equipment components, equipment, and equipment systems for both AC and DC systems. This includes the behaviour of and interactions with, and duties imposed by the network and other system equipment under normal and abnormal conditions, testing and testing technologies, quality assurance, reliability, maintenance and asset management.

This equipment includes all devices for switching, interrupting, or limiting currents (circuit breakers, load switches, disconnect switches, earthing switches, fault current limiters, etc.) independent of technology.  It also includes surge arresters, capacitors, busbar and equip­ment insulators, instrument transformers, bushings, and all other high voltage equipment not specifically covered under another equipment study committee’s scopes.  Emphasis is on function and interaction of high voltage equipment including air and gas-insulated equip­ment, solid insulation used in high voltage equipment, outdoor insulation, and equipment us­ing other insulation systems and interrupting media.


Each Study Committee oversees a number of Working Groups.
