Abstract :
The paper considers a way for extending the bandwidth of integration-type digital voltmeters (DVM) that measure RMS values and harmonic ratios of signals. The method is applicable to measurements within frequency range commonly used for determining power quality parameters. In the course of experimental study the DVM had demonstrated non-uniformity of its amplitude-frequency response less than ±20 μV/V within the 50 to 3300 Hz band.
