Separable toroidal segments reduce the size of a sensing transformer that can be installed on an electrical conductor while connected to a device.

A monitoring device (1) for monitoring the electrical properties of a medium voltage overhead line (3) in a medium voltage network comprises three separate measurement sensors (2a, 2b, 2c), each being adapted for direct connection onto a medium voltage overhead line. Each of the measurement sensors has means to draw operating power from the medium voltage overhead line. The measurement sensors measured results may be combined for accurate measurement analysis.

In a power line takeoff clamp assembly and method of use thereof an electrical power distribution line is clamped to a body of the clamp assembly. A power takeoff supported by the body clamped to the power line generates direct current from alternating current flowing in the power line. One or more sensors supported by the body clamped to the power line sense one or more values related to an electrical current flowing in a power line. A wireless transceiver supported by the body clamped to the power line communicates data regarding the one or more sensed values. Each sensor and the wireless transceiver utilize direct current generated by the power takeoff for the operation thereof.

In a gap-mode waveguide embodiment, an interior gap in a tubular waveguide principally condenses a dominant gap mode near the interior gap, and an absorber dissipates electromagnetic energy away from the gap mode. In this manner, the gap mode may dissipate relatively little power in the absorber compared to other modes and propagate with lesser attenuation than all other modes. A gap mode launched into a gap-mode waveguide may provide for low-loss, low-dispersion propagation of signals over a bandwidth including a multimode range of the waveguide. Gap-mode waveguide embodiments of various forms may be used to build guided-wave circuits covering broad bandwidths extending to terahertz frequencies.

An electronic circuit includes a first substrate having a first substrate surface and a device supported by the first substrate surface. The device is selected from among a passive electronic component and an active electronic component. The electronic circuit also includes a second substrate having a second substrate surface and a conductor proximate to the second substrate. The electronic circuit also includes a magnetic field transducer disposed over the conductor and coupled to the device and an insulating layer disposed between the conductor and the second substrate. The conductor is adapted to carry an electrical current to generate a first magnetic field. The electronic circuit is responsive to the first magnetic field. In some embodiments, the conductor is a secondary conductor and the circuit further includes a primary conductor disposed proximate to the magnetic field transducer and an insulating layer disposed between the primary conductor and the second substrate.

A method of coupling a shunt to a printed circuit board (PCB) of an energy management system is provided. The method includes coupling flexible electrical connectors to the shunt and soldering the flexible electrical connectors to connection points on the PCB of the energy management system. An energy management system that includes a shunt coupled to a printed circuit board using the above method is also provided.

A storage battery includes a battery housing and a plurality of electrochemical cells in the battery housing electrically connected to terminals of the battery. A battery test module is mounted to the battery housing and electrically coupled to the terminals through Kelvin connections. A display or other output is configured to output battery condition information from the battery test module. The battery test module is configured to automatically carry out a battery test when a voltage across the battery falls below a predetermined threshold.
