IEEE Approves Projects To Create Standards For Ultra-High-Voltage Electric Systems
New standards will address voltage and reactive power, acceptance tests and overvoltage and insulation coordination related to systems of 1000kV or more
Piscataway, N.J - IEEE, the world's largest professional association advancing technology for humanity, today announced that the IEEE Standards Association (IEEE-SA) Standards Board has approved three projects for the creation of standards for 1000kV-or-greater, ultra-high-voltage (UHV) electric systems.
When completed, IEEE P1860 – Standard for Voltage and Reactive Power in 1000kV or Greater (Ultra High Voltage) AC Systems – will specify basic requirements of voltage and reactive power, allowed voltage deviation, as well as technical measures for voltage and reactive power allocation and adjustment in UHV AC transmission and transformation systems and the power sources connected into them. The intent of this standard is to establish criteria for electric departments in the planning, design, infrastructure, operation and scientific research of an UHV AC system.
IEEE P1861 – Standard for Acceptance Tests on Sitehand-Over Test of 1000kV or Greater (Ultra High Voltage) AC Electric Equipment and Commissioning Procedures – will establish criteria and requirements for test items, conditions, methods and results of acceptance tests on sites of UHV electric equipment. This equipment might include power transformers, reactors, capacitor voltage transformers, current transformers, gas-insulated switch apparatus, earthing switches, bushing, arresters, suspension insulators and pillar insulators, insulating oil, SF6, secondary circuits, overhead power lines and grounding devices.
IEEE P1862 – Standard for Overvoltage and Insulation Coordination of 1000kV or Greater (Ultra High Voltage) AC Transmission Projects –will apply to three-phase UHV AC systems and specify the procedure for selection of the rated withstand voltages of equipment and transmission line insulation in project construction.
