发明名称 STRAY VOLTAGE DETECTING
摘要 A stray voltage detector has a portable housing carrying a pair of electrostatic charge sensors spaced apart along an axis, and a pair of field intensity indicators, each indicator connected to an associated one of the charge sensors and constructed to indicate a relative electric field intensity at its associated sensor. The voltage detector is constructed to provide simultaneous electric field intensity feedback from both indicators to an operator moving the housing along the axis over a surface with a localized region at an elevated voltage, to assist in locating the localized elevated voltage region. The detector is useful for locating high-voltage regions, even when there is little or no current flowing through such regions to generate a magnetic field.
