Abstract :
This paper presents a digital instrument for the power quality analysis in systems where voltage or current waveforms are nonsinusoidal. It is based on a C40 DSP and on a special high-speed data acquisition system. The analysis is performed by a recursive algorithm which allows the mutable system properties to be tracked on-line. The paper also goes on to discuss the performance of an instrument prototype, both in terms of accuracy and speed of measurement
