摘要： Current flowing into and out of a battery (1) installed in a vehicle (V) with the required cable (3) between one of the battery terminals and a reference point (8) on the vehicle is determined by measuring the voltage across the cable (3) and computing (22) the current from the digital value of the measured current. The resistance value of the cable can be known in which case the current is computed using Ohms low and a differential current sensor (30) can be used to respond to the voltage measured across the cable to accommodate for different ranges of current. In an embodiment where the cable (3) resistance is unknown, a reference current source (125) produces a known voltage (128) that is used to set the input value to an amplifier (111) of fixed gain for the voltage measured across the cable by controlling the output of a potentiometer (106) so that the amplifier output voltage can be set to match the reference current generator output voltage, thereby establishing the voltage output of the amplifier as a measurement of the current flow in the cable.

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： A system for locating a circuit interrupter, e.g. a circuit breaker, associated with a selected branch circuit (40-45) from amongst a plurality of circuit interrupting devices, CB1-CB6. The system includes a receiver (300) and a passive transmitter (100). The passive transmitter (100) when electrically connected to a branch circuit creates a current spike signal on that circuit at a predetermined frequency. This current spike signal has a sufficiently short spike duration so as to only generate a weak electromagnetic field about the circuit wire, which in turn, substantially minimizes the development of a sympathetic signal on other branch circuits adjacent to the selected branch circuit. Thus, the true current spike signal is easily distinguishable from any sympathetic signals. Accordingly, the receiver (300) can be broadly tuned about the predetermined frequency of the current spike signal and drives a user-perceivable signaling device upon sensing the current spike signal. A method for locating a circuit interrupter is also disclosed.

摘要： An automatic power turn-on circuit for a battery-powered measurement instrument. Instrument power is normally off, and when the instrument is connected to a voltage to be measured, the voltage that is sensed activates an electronic switch that in turn connects an internal battery to the processing and display circuits of the instrument. The voltage sense circuitry includes circuits for sensing either a positive or a negative voltage, and basing a driver transistor into conduction. The driver transistor in turn activates the switch to connect the battery voltage to a power supply output node. An RC network holds the switch in the "on" position for a short period of time after the voltage to be measured is removed from the inputs of the instrument.

摘要： A circuit testing device (10) of the insulation piercing type comprises a hollow outer sleeve (14) having a hook member (16) at one end for hooking over a wire to be tested and a jaw member (22) slidable in the sleeve member between a retracted position and an advanced position in which it opposes the hook member (16) to grip a wire between the hook (16) and jaw member (22). A conductive probe (26) having a pointed end is slidable axially in the jaw member (22) between a retracted position and an advanced position in which it contacts any wire held between the hook (16) and jaw member (22), piercing any insulation covering the wire. The segment of the hook member (16) which opposes the probe (26) has no holes in order to provide solid support backing to the wire to be tested, to prevent damage to the wire and to insure good contact by the probe (26). A manually operable actuator successively moves the jaw member (22) and probe (26) into their advanced positions, and a is provided to maintain any such advanced positions. A signaling device such as a lamp bulb (44) connected to the probe (26) indicates the existence of any electrical current passing through the wire contacted by the probe (26).

摘要： Self contained radio transmitting state estimator modules are mounted on power conductors on both sides of power transformers in electrical substations and on power conductors at various places along electrical transmission lines. They are electrically isolated from ground and all other conductors. These modules are capable of measuring current, voltage, frequency and power factor (or the fourier components thereof) the temperature of the conductor, and the temperature of the ambient air. The modules transmit these parameters to local receivers. The receivers are connected by an appropriate data transmission link. to a power control center which allows determination of the state of the power system. Appropriate control signals are transmitted back to the electrical switchgear of the system to bring it to the appropriate optimum state. Direct local control may also be effected, for example, the prevention of overloading a transformer. A donut state estimator module comprises a novel hot stick operated hinge clamp and a novel voltage sensor which measures the current between an isolated capacitor plate and ground. The donut measures the fourier components of voltage and current over a number of cycles and transmits the components to the local receiver. The local receiver derives the desired electrical measurements such as voltage, current, power factor, power, and reactive power and transmits them to local or remote control stations. Up to 15 donut modules may transmit on a single channel to a single local receiver. Each transmits at intervals which are an integral number. The intervals between transmissions of all donuts do not have a common factor and the average interval is the desired transmission rate. Each donut uses the zero crossover of current of its conductor to establish its transmission interval. The system is self- calibrating using known reference signals within the donut module.
