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.

This guide applies to on-site acceptance tests of electrical equipment and system commissioning of
1000-kV ac and above. It identifies criteria and recommendations for test items, conditions, methods, and results.
The stated recommendations, both technical and for testing, are universally needed for on-site acceptance tests and commissioning of 1000 kV ac and above ultra-high-voltage (UHV) power equipment, including power transformers, reactors, capacitive voltage transformers (CVTs), bushing-type current transformers (CTs), gas-insulated switchgear, air insulated grounding switches, air insulated disconnecting switches, bushings, metal-oxide surge arresters (MOSAs), suspension insulators, post insulators, and insulating oil.
The intent of this guide is to identify on-site acceptance tests of 1000-kV ac and above electrical equipment. This guide also promotes the application and development of on-site acceptance test methodology. This guide also provides uniform technology specification recommendations for commissioning of 1000-kV ac and above transmission systems. It also provides the recommendations of testing, acceptance criteria, and safety specifications. This guide also provides sufficient technical support for widespread and long-distance UHV ac transmission and promotes system operating safety and reliability.
