Abstract

PURPOSE: To prevent the conductive sheath from going to high voltage, by grounding the conductive sheath of cable through a resistor and suppressing the high frequency current induced in the conductive sheath by switching surge.
CONSTITUTION: The conductive sheath 23 of cable connected to the gas insulated switchgear 21 is grounded through a matching resistor 25. Since the travelling wave induced in the sheath 23 during occurrence of switching surge is impedance matched by the matching resistor 25, high frequency current is not generated thereby the cable sheath 23 is brought to high voltage to prevent the flushing to other grounding system.
