PURPOSE: An integrated subway control panel gas-insulated switchgear local controlling panel digital system (GLDS) is provided to perform a quick and accurate analysis by digitizing a local control system. CONSTITUTION: Gas-insulated switchgear (GIS) (200) receives external power. The external power is delivered through a power-receiving line. A transformer receives a current outputted from the GIS. The transformer transforms the current into a fixed voltage value. A GLDS locally controls the GIS.
