    摘要: A flexible current and voltage sensor provides ease of installation of a current sensor, and optionally a voltage sensor in application such as AC branch circuit wire measurements, which may require installation in dense wiring conditions and/or in live panels where insulating gloves must be worn. The sensor includes at least one flexible ferromagnetic strip that is affixed to a current sensing device at a first end. The second end is secured to the other side of the current sensing device or to another flexible ferromagnetic strip extending from the other side of the current sensing device to form a loop providing a closed pathway for magnetic flux. A voltage sensor may be provided by metal foil affixed to the inside of the flexible ferromagnetic strip. A clamp body, which can be a spring loaded handle operated clamp or a locking fastener, can secure the ferromagnetic strip around the wire.

    摘要: Calibration of a non-contact current sensor provides improved accuracy for measuring current conducted through a conductor such as an AC branch circuit wire. In a calibration mode, a predetermined current is injected through a voltage sensing conductor integrated in the non-contact current sensor. The magnitude of the magnetic field is measured using a sensing element of the non-contact current sensor. Then, when operating in measurement mode, a current conducted in a wire passing through the non-contact current sensor is determined by correcting the output of the non-contact current sensor using the result of the measurement made in the calibration mode. The voltage sensing conductor is used to provide an indication of the magnitude and/or the phase of the electrostatic potential on the wire. The calibration current may be a DC current, and calibration may be performed while the conductor is carrying an AC current.

    摘要: A method, system, and computer program product for relating a data processing system with a power branch circuit are provided in the illustrative embodiments. Each signal in a set of signals is combined with a power signal to form a set of combination signals, the power signal including a first power usage by the data processing system and a second power usage by a modulating signal. An amplitude of a corresponding signal in each combined signal in the set of combined signals is determined over a period. Using a discriminating logic, a determination is made whether the modulating signal is present in the power signal. Responsive to the discriminating logic producing an affirmative result, the data processing system is related with the power branch circuit.

    摘要: Calibration of a non-contact voltage sensor provides improved accuracy for measuring voltage on a conductor such as an AC branch circuit wire. In a calibration mode, a predetermined voltage is imposed on a first voltage sensing conductor integrated in the non-contact voltage sensor, while a voltage on a second voltage sensing conductor is measured using a circuit of predetermined input impedance. The capacitance between the wire and each of the voltage sensing conductors may be the same, so that in measurement mode, when the first and second voltage sensing conductors are coupled together, the effective series capacitance provided in combination with the predetermined input impedance is four times as great. The results of the voltage measurement made in the calibration mode can thereby be used to adjust subsequent voltage measurements made in measurement mode with the first and second voltage sensing conductors combined in parallel.
