Measurement of electrostatically induced voltages in two metal boxes using spark gaps and electromagnetic wave sensors

Electrostatically induced voltages are generated in metal boxes when a charged human body moves near boxes that have openings. The induced voltages occasionally cause malfunction and failure of electronic equipment. When a human body walks in office that uses air conditioner, the body is electrified. Hence, when a charged body, such as charged human body, moves near metal boxes, high induced voltages are generated in them. In the experiments, two metal boxes similar to the boxes of electronic equipment are used. The induced voltages generated in the two metal boxes are measured. The results will help to resolve electrostatic problem.
