Methods, systems, and apparatus, including computer programs stored on a computer-readable storage medium, for obtaining, from an electric field sensor, measurements of a net electric field resulting from a combination of respective electric fields from two or more electrical power conductors that are proximate to the electric field sensor. The apparatus detects a change in successive measurements of the net electric field. The apparatus determines, based on the change, that an electrical fault has occurred in one of the two or more electric power conductors. The apparatus sends to a server system, data indicating that the electrical fault has occurred in one of the two or more electric power conductors.

The present disclosure relates to a semiconductor apparatus and a potential measuring apparatus capable of preventing deterioration in signal characteristics due to parasitic capacitance caused by providing a configuration for realizing an electrode plating process when an electrode and an amplifier are provided on the same substrate. When a power source supplies a potential necessary for plating processing and a breaker reads a signal from liquid, and an amplifier amplifies and outputs the signal, the power source required for the plating processing is blocked with respect to the electrode. This is applicable to the potential measuring apparatus.

The inventive wrist-band voltage detector provides a wearable device for detecting the presence of AC voltage without interference with work activities. Embodiments of the inventive wrist-band voltage detector include monopole aerials positioned in each side of the wrist band. A thin flexible dielectric layer may sit between the aerials and inside of the wrist band, acting as an electrical barrier between the aerials and the user's wrist. The aerials are connected to conventional voltage detector circuitry on a circuit board located on the top side of the wrist band. The circuit board is grounded to the user's wrist, which enhances the circuitry's ability to detect the presence of nearby AC voltage at a safe distance.
