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 . The IEC Standards for High Voltage Equipment Testing provide a benchmark for manufacturers, utilities, and testing laboratories around the world. It is known by a number of names such as dielectric (strength) test, dielectric voltage-withstand test, flash test, high potential ("HiPot") test or isolation test. The aim of the second group of tests on service-aged equipment, the so-called diag-nostic tests, is related to the condition assessment of insulation for t e estimation of the remaining lifetime. IEEE Guide for On-Site Acceptance Tests of Electrical Equipment and System Commissioning of 1000 kV AC and Above IEEE Guide for On-Site Acceptance Tests of Electrical Equipment and System Commissioning of 1000 kV AC and Above Sponsored by the Corporate Advisory Group IEEE Substations Committee.
