Filed: 1987-02-26
Abstract: PURPOSE:To enable highly accurate locating of a fault point without subdivision of a container in a long-sized bus, by determining a propagation time difference in an impulsive pressure wave to pressure sensors at both ends in a bus container as generated when a fault occurs. CONSTITUTION:It is assumed that a fault occurs at a desired point A in a bus container 1, arc energy of a fault current causes a rise in the temperature of a gas near the fault point to generate an impulsive pressure. As pressure wave, the impact pressure propagates horizontally through a gas space. When the impulsive pressure wave reaches the positions of pressure sensors 14 and 15, the pressure sensors 14 and 15 generate detection signals, which are read out with a time difference detector 16 as electrical signal to determine a time difference. Then, the fault point A is located by calculation with a fault point locator 17 from relationship between the time difference and the propagation speed of the impulse pressure wave in the gas.
