Abstract :
With lOOOkV transmission lines planned in Japan,
very fast transient (VFT) phenomena will be suppressed
by installing a resistor in a disconnector Of gas insulated
switchgear (GIs). In this paper the VFT overvoltage suppressing
effect of the resistor and the duty required of the resistor
are clarified. A llOOkV resistor-fitted disconnector was tested
by constructing a charging current interruption test circuit. It
has been clarified that the disconnector accepts the required
duty. The disconnector tested here will be used for the field
test.
