摘要： 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.

摘要： A system and method for detection of a fault in a component of an Alternate Current Motor (ACM) based on current samples of the ACM. The system includes a current sensor for sampling a current of the ACM. The sampling is performed a plurality of times within a half-wave form of an Alternate Current (AC) of the ACM and over several cycles of half-waves. The system also includes a computing device for receiving the plurality of current samples. The computing device is configured to analyze a plurality of current samples of the AC of the ACM, the plurality of current samples taken for at least several periods of half-waves of the AC, determine, based on the analysis of the plurality of current samples, whether the ACM is a Variable Frequency Drive (VFD) or a non-VFD, and report that fault detection cannot be made if the ACM is a VFD.

摘要： An apparatus and method for identification of air leaks in a compressed air system are presented. The method includes receiving system data including current samples of air compressors of the compressed air system from at least one self-powered power sensor; aggregating the system data; dividing the aggregated system data into a plurality of clusters; merging overlapping clusters to reduce the number of clusters to two clusters, wherein a first cluster represents a baseload current and a second cluster represents a full-load current; determining the baseload current to full-load current ratio and comparing the ratio to a predetermined standard; and determining if an air leak is present if the ratio is below the predetermined standard.

摘要： 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.

摘要： 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.
