MEASUREMENT DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/021592
Kind Code:
A1
Abstract:
This invention makes it possible to measure a current in synchronization with a voltage without measuring the voltage. A device having a prescribed current pattern that appears in synchronization with a current frequency is connected to a power supply line from a distribution board. The prescribed current pattern is detected from a current waveform measured using an ammeter that measures the current at the distribution board. Information about the voltage phase at the distribution board is acquired.
