An AC Controlled-Current Load for Controllable Waveform Parameters to Quantify Static Energy Meter Errors

This paper proposes a method for quantifying static energy meter errors using current waveform parameters. This will be realized via a controlled-current load, for which the design is given. Several parameters like the rise time, current slope, crest factor and phase firing angle are considered to identify relations which cause static energy meter measurement errors. Some of these parameters are also used as a way to verify the functionality of the controlled-current load in a quantitative manner. This is realized by comparing these parameters for the original and reproduced current waveform, where a feedback capacitor is used to optimize the system tailored to which parameter is deemed most crucial.
