WP-TRMS true effective value transmitter

At present, most of the current and voltage meters on the market use simple rectification and averaging circuits to measure AC signals, which have significant theoretical errors. Therefore, these instruments can only be used to measure the effective value of standard undistorted sine waves. If it is a non sinusoidal waveform or a distorted sine wave, the measured result does not match the actual value of the signal. The true effective value transmitter adopts the average technique of signal square integration, which is used for accurate measurement of various noises such as standard sine waves, non periodic, non sine waves, and superimposed DC levels, without considering waveform parameters and distortion, which cannot be achieved by average measurement instruments.
