Publication number: 20240329088Abstract: The present disclosure provides a voltage detector capable of alerting a worker to nearby presence of a voltage source regardless of the worker's awareness simply by being worn on the worker's body. In a voltage detector for detecting approach to a voltage source, a voltage induced in a human body due to approach to a voltage source is measured by a first electrode of a detection circuit, a voltage to ground is measured by a second electrode of the same circuit, the detection circuit captures a current generated due to a difference between an electric potential of the first electrode and an electric potential of the second electrode, and output from the detection circuit is displayed for warning when the human body insulated from the ground approaches the voltage source.Type: ApplicationFiled: March 29, 2023Publication date: October 3, 2024Inventors: Yoji Oura, Masami Kojima, Masakatsu Sawada, Ryuzo Noda, Kazuaki Matsuo
