초록

The clarification of insulation capability of GIS(Gas Insulated Substation) under very fast transient overvoltages such as disconnector/circuit-breaker induced surge is very important for establishing not only a rational insulation testing method, but also insulation design intending to make GIS more reliable and more minimized. One of the absolute prerequisits for this is that more accurate measurement of VFTO. This describes capacitive voltage measuring methods for high voltage steep-footed oscillating waves using capacitive coupling principle and their systems including source and load impedances. Time domain response of unit step and its frequency characteristics are also investigated.
