GIS FIELD OSCILLATION TYPE IMPULSE WITHSTAND VOLTAGE TEST WAVEFORM ADJUSTMENT SYSTEM AND METHOD

摘要

A GIS field oscillation type impulse withstand voltage test waveform adjustment system and a method. The method comprises the following steps: calculating a capacitance value of a tested GIS (S101); determining a test waveform parameter value (S102); calculating a test loop parameter based on the capacitance value of the tested GIS and the required test waveform parameter value (S103); establishing a test line based on the loop parameter obtained from calculation (S104); and using the established test line to perform an oscillation type impulse withstand voltage test on the GIS (S105). The waveform adjustment method can obtain a parameter of the test waveform before performing a formal high voltage test, avoiding blindness of the test; and a numerical calculation method is used to calculate the test loop parameter, providing advantages of high calculation accuracy and facilitating implementation. The system has advantages of easy to use and facilitating field implementation.
