The electrical interface includes an input that is configured to sample an input voltage signal from the Rogowski coil. The electrical interface also has an integrator circuit which includes an integrator module that is configured to integrate the sampled input voltage signal to provide an output voltage signal from which can be derived a primary current flowing through the primary conductor. The integrator module employs a transfer function that includes an attenuation factor.

摘要： Apparatus and techniques for controlling measurement of an electrical parameter of an energy source can be used to obtain information for use in enhancing a power transfer efficiency between the energy source and a load. For example, during a first measurement cycle, information indicative of the electrical parameter of the energy source can be obtained using a measurement circuit during a first sampling duration in which the load is decoupled from the energy source. The information indicative of the obtained electrical parameter can be compared to a threshold. In response to the comparing, a different second sampling duration can be determined for use in obtaining information indicative of the electrical parameter during a subsequent measurement cycle. The information indicative of the electrical parameter of the energy source includes information for use in enhancing the power transfer efficiency between the energy source and the load.

摘要： Systems and methods for identifying and reporting failures of an analog to digital (A/D) conversion system are presented. The systems and methods may detect and report a problem of input circuitry of an A/D converter and/or an A/D converter itself. For example, an identifiable characteristic can be introduced into the input signal provided to an A/D converter. The A/D converter may output a digital value that includes the identifiable characteristic of the A/D converter input. A monitoring system may determine and/or report a change in, or a failure of, the A/D converter or input circuitry thereto, based on the identification, non-existence of, or variation in the identifiable characteristic in the digital output.

摘要： An apparatus for AC physical signals measurement and data acquisition and the method for the same are provided. The apparatus for AC physical signals measurement and data acquisition comprises an analog sampling channel for inputting an AC signal and outputting an analog sampling value; a sampling switch for performing re-sampling to obtain data frequency as required by the receiving side; a register for storing a re-sampling value from the sampling switch; a bus for outputting the re-sampling value in the register to the receiving side; a timing controller for controlling the analog sampling channel and the re-sampling frequency of the sampling switch; and a digital low-pass filter, which has an input connected with the analog sampling value outputted by the analog sampling channel and an output connected with the sampling switch, filters out high frequency components from the sampling value, and has a cut-off frequency that should be lower than 0.5 times the re-sampling frequency of the sampling switch. The apparatus and method for AC physical signals measurement and data acquisition improve accuracy of remote measurement for electric power physical quantities. Not only waveform values are outputted by re-sampling, effective values, steady state values and their fundamental/harmonic wave effective values and steady state values are also outputted. Thus, various requirements by the receiving side on remote measurement data are satisfied.
