Abstract

PURPOSE: To immediately identify a defective section, by effectively detecting the rise in gas pressure due to a ground fault with a defective position detector employing a strain gauge.
CONSTITUTION: The detector 12 is installed at each section chamber. When the ground fault occurs at a section chamber, the gas pressure rises by about 0.02 to 0.4 kg/cm2. The displacement of a diaphragm 11 due to the pressure change is detected by the strain gauge 10 to identify the defective section chamber.
