Title:
WAVEFORM SPLITTER
Document Type and Number:
WIPO Patent Application WO/2019/076164
Kind Code:
A1
Abstract:
The present invention relates to a waveform splitter, comprising a first electronic switch, a second electronic switch and a control module. The first electronic switch and the second electronic switch are separately connected to a current input end. The control module is separately connected to a control end of the first electronic switch and a control end of the second electronic switch. The control module is used for controlling either the first electronic switch or the second electronic switch to open in a random on/off maintenance period. The first electronic switch and the second electronic switch can split the sine-wave current inputted by the current input end into two non-linear waveform currents, thus enabling a tested meter to measure the non-linear waveform currents. A primary circuit can synthesize the non-linear waveform of two branches into the sine-wave waveform current. The measurement of a conventional standard meter on the primary circuit sine wave can be employed to check the measurement of the tested meter on the non-linear waveform, thus determining whether the measurement is credible or not. Because the conventional standard meter measures the sine wave with standard traceablility, and therefore standard traceablility for non-linear waveform measurement can be realized.
