Abstract

PURPOSE: To perform safe power detection of high potentials with a simple and small size constitution by indirectly detecting the power from the electrostatic induction voltage between a high potential part and antenna.
CONSTITUTION: The current corresponding to the voltage applied to a potential part 1 is flowed in a detection resistance 6 by the electrostatic induction voltage through an antenna 2 of sharp directivity which is spaced at a specified distance from the high potential part 1. When the voltage of the resistance 6 proportional to this current is displayed in a display circuit 8 connected to an amplifier circuit 7, the detection of high voltages may be performed safely with the simple and small constitution without directly touching the high potential part.
