  • Non-contact voltage measurement device
    Patent number: 10145865
    Abstract: Provided is a non-contact voltage measuring device capable of measuring, with given accuracy, measurement target voltages applied to various conducting wires having respective different shapes. An inner electrode which is deformable depending on a shape of a wire “w” is electrically connected, via a connecting section, to an outer electrode fixed to an electric field shield.
    Type: Grant
    Filed: February 4, 2015
    Date of Patent: December 4, 2018
    Assignee: OMRON CORPORATION

  • Measurement device and mounting unit
    Patent number: 9915689
    Abstract: A measurement device has a sensor that generates current by electromagnetic coupling to a power line, a measurement circuit that measures one of voltage and power, the voltage and the power being obtained by the current generated in the sensor according to voltage at the power line, a conductive member electrically connected to a signal ground line of the measurement circuit, and an insulating member that brings the conductive member close to an external conductor and insulates the conductive member from the external conductor.
