Abstract
PURPOSE: To improve the efficiency of survey, by enabling the constant application of prescribed pulses even if the resistance of a load varies.
CONSTITUTION: A voltage Vd produced by dividing the terminal voltage of a power capacitor 12 through resistors 21, 22 is compared with a reference voltage e by a comparator 23, which generates a trigger pulse VT when the voltage Vd has exceeded the reference voltage e. If the voltage Vd has exceeded the reference voltage e in charging, the comparator 23 produces a trigger pulse VP. When the charging voltage has a prescribed level VC, a vacuum switch 13 is actuated so that the voltage of the high-voltage pulse Vp which is the output of the switch becomes constant despite the magnitude of the grounding resistance on a trouble point. Therefore, the prescribed pulses can be always applied to the load even if the resistance of the load varies.
