Patent number: 11705275Abstract: A current transformer (CT) for the purpose of, for example, current measurement, that uses a power line as a first coil and a second coil for measurement purposes, is further equipped with a third coil. Circuitry connected to the third coil is adapted to measure a signal therefrom. The measured signal from the third coil is compared to a signal measured from the second coil and based on the results, internal CT parameters are determined allowing calibration of actual results to expected results thereby providing an improved accuracy. This is especially desirable when using the CT for measurement of the like of current or phase of the primary coil when measurements are adjusted using the newly determined calibration parameters.Type: GrantFiled: November 19, 2020Date of Patent: July 18, 2023Assignee: PANORAMIC POWER LTD.Inventors: Daniel Aljadeff, Dan Wijsboom, Yael Alali, Adi Shamir

Patent number: 11538628Abstract: A current transformer (CT) for the purpose of, for example, current measurement, that uses a power line as a first coil and a second coil for measurement purposes, is further equipped with a third coil. Circuitry connected to the third coil is adapted to inject a known reference signal to the third coil of the CT. The injected reference signal, i.e., current, generates signals in the first and second coils of the CT. The signal generated in the second coil is compared using circuitry attached thereto to the reference signal. Based on the results, and the difference between the expected results and the actual results, updated calibration parameters are determined. These provide improved accuracy when using the CT, for example for measurement of the like of current or phase of the primary coil when measurements are adjusted using the newly determined calibration parameters.Type: GrantFiled: November 19, 2020Date of Patent: December 27, 2022Assignee: Panoramic Power Ltd.Inventors: Daniel Aljadeff, Dan Wijsboom, Yael Alali, Adi Shamir

Patent number: 10024885Abstract: A method is provided for handling the heating resulting from the operation of a self-powered power sensor (SPPS). The SPPS periodically switches between a sense mode and a harvest mode, each contributing to power dissipation that translates into heat, which may become a safety hazard. A duty cycle that is the ratio between the period in which sensing take place and the total time elapsed between sensing periods defines the duty cycle of the SPPS. In order to prevent overheating of the SPPS it is configured to provide a dynamic duty cycle that is higher for lower currents in the primary power wire and lower, for higher primary currents. This allows for better power dissipation of the SPPS and removing it from operation in unfavorable or dangerous conditions.Type: GrantFiled: January 9, 2018Date of Patent: July 17, 2018Assignee: Panoramic Power Ltd.Inventors: Adi Shamir, Dan Wijsboom, Yael Alali, Lior Baz

Patent number: 9720017Abstract: Apparatus and methods are provided for the measurement of power consumption at points of interest, such as circuit breakers, machines, and the like. Accordingly, means are provided for measurement of power consumption for each electrical sub-network that is controlled by a circuit breaker. Each apparatus is enabled to communicate its respective data, in an environment of a plurality of such apparatuses, to a management unit which is enabled to provide finer granularity power consumption profiles. Challenges of measuring relatively low supply currents, wireless operation in an environment of a large number of apparatuses, and self-powering are addressed.Type: GrantFiled: June 21, 2013Date of Patent: August 1, 2017Assignee: Panoramic Power Ltd.Inventors: Adi Shamir, Dan Wijsboom, David Almagor
