  • High-voltage field testing of GIS from a physical view

    Abstract: GIS (gas-insulated substation) field tests are recommended. For GIS of lower rated voltage (245 kV), where mainly free-moving particles are dangerous, an AC voltage test including sensitive PD (partial discharge) measurement is shown to be efficient.The PD measurement can be replaced by an OLI (oscillating lightning
