A device for simulating high-frequency current propagation of partial discharge of a GIL/GIS is disclosed. The device comprises a casing, a busbar cavity, an adjustable impedor, a first metal support, a second metal support, a third metal support, and a high-frequency current sensor. The first metal support and the second metal support are separated by an insulating support, the third metal support has an end connected to the second metal support, as well as an end connected to a grounding grid, and the adjustable impedor is formed by an adjustable resistor and an adjustable inductor which are connected in series, and is connected in series between the first metal support and the second metal support through a wire. In the application, the adjustable impedor is connected in series to the metal supports at the grounding point to obtain an impedance equivalent to that of a long-distance GIL/GIS housing.
