摘要（英）：

In order to reduce disadvantageous influence caused by electromagnetic interference, improve the accuracy of measurement and provide a shielding device for measuring the transient shell voltage of a gas insulated switchgear (GIS) when the GIS is measured, the invention provides a system for measuring the transient shell voltage of the GIS. The system is characterized by comprising a measuring cable, a voltage measuring device and a measured data processing system, wherein the measuring cable is connected between a shell of the GIS and the voltage measuring device; the voltage measuring device is used for measuring the voltage of the shell of the GIS; the measured data processing system is used for processing the measured data from the voltage measuring device; and the measuring system comprises the shielding device which is used for wholly shielding the measuring cable, the voltage measuring device and the measured data processing system. Through the technical scheme, the shielding device for measuring the transient shell voltage of the GIS is provided; the influence of the electromagnetic interference is reduced; and the accuracy of measurement is improved.
