IEEE 1861-2014 - IEEE Guide for On-Site Acceptance Tests of Electrical Equipment and System Commissioning of 1000 kV AC and Above
On-site acceptance tests of ultra-high-voltage power equipment are subject to this guide. Criteria and requirements for test items, conditions, methods, and results are established. The stated specifications and requirements, both technical and for testing, are universally needed for acceptance tests on-site and commissioning of ultra-high-voltage power equipment, including power transformers, reactors, capacitive voltage transformers, bushing-type current transformers, gas-insulated switchgear, air insulated grounding switches, air insulated disconnecting switches, bushings, metal-oxide surge arresters, suspension insulators, post insulators, and insulating oil, etc. It will be sufficient for most installations.
IEEE 1862-2014 - IEEE Recommended Practice for Overvoltage and Insulation Coordination of Transmission Systems at 1000 kV AC and Above
This recommended practice specifies the procedure for selection of insulation levels of UHV AC transmission lines and substations. It also specifies reliability criterion under switching overvoltage and lightning overvoltage. It also suggests the calculation methods of insulation coordination design. According to the characteristics of UHV AC systems, overvoltages mitigation measures are recommended. Some examples of insulation coordination are presented.
