摘要： A non-contact electric potential meter system to determine voltage between an AC conductor and a reference potential without direct electrical contact to the conductor. A housing provides a shielded measurement region that excludes other conductors and holds power supply means; an AC voltage sensing mechanism includes a conductive sense plate and an electrical connection to the reference potential. Waveform-sensing electronic circuitry obtains an AC voltage waveform induced by capacitive coupling between the conductor and the conductive sense plate. Capacitance-determining electronic circuitry obtains a scaling factor based on the coupling capacitance formed between the conductor and the conductive sense plate. Signal processing electronic circuitry uses the AC voltage waveform and the coupling capacitance-based scaling factor to obtain the voltage between the conductor and the reference potential.

摘要： The invention draws upon an insight that if the distance between the Sensing Points of a shunt is precisely defined and is repeatable (for example, due to the punching tool used to create the holes for the Sensing Points), then accurate calibration and determination of the Thermal Compensation function of the shunt can be done by means of a single measurement at room temperature. Saying this differently, once the calibration according to the invention has been carried out, the shunt can be used to achieve very accurate current measurements at any of a range of temperatures, and yet (perhaps counter-intuitively) the calibration itself only needs to be carried out at a single temperature.

摘要： Systems, methods, and an apparatus for current monitoring are disclosed. A current monitor comprises a high-voltage side configured to obtain a signal indicative of current through a conductor and apply different levels of gain to different frequency bands of the signal to produce an adjusted signal. A low-voltage side of the current monitor is electrically isolated from the high-voltage side and is configured to split the adjusted signal to produce a plurality of output signals that are each indicative of a level of current at one of the different frequency bands. An isolation amplifier is configured to communicate the adjusted signal from the high-voltage side to the low-voltage side while electrically isolating the high-voltage side from the low-voltage side.
