IEEE 1861-2014

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.
