Abstract
At present, the testing method of CT mainly have 3 kinds, load extrapolation traditional up flow method, low voltage test method and traditional low voltage method. Because of limitation of test theory, test method, test site GIS CT has been testing circuit, impedance, the test current difficult to code requirements, problems and difficulties. This paper introduces a new kind of GIS type CT scene matching technology to achieve the impedance frequency conversion technology, small signal testing technology, testing technology, can solve the problems of field test and large capacity requirements, error due to the interference, the test lead length.关键词
