    摘要： The invention concerns a magnetic measurement device comprising a DC magnetic field sensor consisting of at least four discrete elongate elements, each element consisting of at least one coil and a magnetic material without remanence, said discrete elements being substantially identical; characterised in that the magnetic field sensor comprises: - a first discrete element oriented along a given axis, a second element being associated with same in order to form a first differential pair oriented along a substantially identical axis but in opposing directions, and - two other elements forming a second differential pair substantially identical to the first but oriented once more along an axis substantially identical to the axis of the first pair but in respectively opposing directions.

    摘要： A contactless apparatus for detecting voltage and current statuses on conductors of electrical equipment in an electric power system. The apparatus detects whether the conductors are in a voltage mode or a current mode by detecting vibrations of the conductors from a distance. The apparatus irradiates a laser beam on the conductors, detects the vibration, and provides result to an output unit such as a display. In addition, a vibration is forcefully produced on the conductors upon irradiating an electromagnetic wave of selected frequency by an electromagnetic wave generator of the apparatus.

    摘要： 57 An apparatus and method for detecting an AC power failure condition employs a fast attack, slow decay, energy storage circuit (28) for tracking an AC input signal and for providing a slowly decaying output based upon a last received peak voltage input value. A current detection circuit (50) monitors the current flow to the storage circuit from the AC mains (72, 74) and generates a current detection signal in response thereto. A power failure condition is declared when either the voltage across the energy storage circuit decays below a selected threshold value or current is not detected flowing to the energy storage circuit at a selected time. A particular current detection circuit (200) employs a high permeability core (201) which is saturated by a current in the sensed line having a current value below an expected peak current flowing to the energy storage circuit. An interrogation pulse periodically energizes an interrogation winding which, in the absence of current in the sensed line, induces a signal across an output winding. When the current being sensed is sufficient to saturate the core, no output signal is generated across the output winding. Circuitry monitors the voltage across the output winding and generates a conditioning signal when even a selected minimum current is not detected in the line at the time of the interrogation pulse.
