Title:
MEASUREMENT DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/021600
Kind Code:
A1
Abstract:
This invention makes it possible to analyze a current waveform measured without measuring voltage. In this invention, an AC current waveform measured using an ammeter is converted to a frequency domain through a Fourier transform, the overall phase components are adjusted so that AC power supply frequency components become zero, a gain and the adjusted phase components are subjected to an inverse Fourier transform, and a time-domain current waveform is output.
