  • SLOTTED CURRENT TRANSDUCER USING MAGNETIC FIELD POINT SENSORS
    Publication number: 20110121827
    Abstract: A current transducer is disclosed that is capable of measuring DC or AC currents in a conductor. The transducer housing has one or more slots into which a conductor is located. The current transducer maintains accuracy independent of the conductor position.
    Type: Application

  • Temperature sensor and extensometer for electrical power cables
    Patent number: 7845848
    Abstract: A thermometer and extensometer for cables and conductors is described. The travel time of one or more acoustic signals along a conductor is used to determine the temperature along the conductor and the length of the conductor. The acoustic frequency is selected to minimize temporal dispersion of the propagating acoustic energy. The technique can be used to measure the temperature of the conductor in a buried, undersea or submerged electrical power cable.

  • Temperature sensor and extensometer
    Patent number: 7575371
    Abstract: A thermometer and extensometer for cables and conductors is described. The travel time of one or more acoustic signals along a conductor is used to determine the temperature along the conductor and the length of the conductor. The acoustic frequency is selected to minimize temporal dispersion of the propagating acoustic energy. The technique can be used to measure the temperature and sag of an overhead power line, the temperature of the windings in a transformer, or the temperature of the central conductor in a coaxial power cable.

  • Power supply
    Patent number: 7304872
    Abstract: A modular, low weight impedance dropping power supply with battery backup is disclosed that can be connected to a high voltage AC source and provide electrical power at a lower voltage. The design can be scaled over a wide range of input voltages and over a wide range of output voltages and delivered power.
