A new instrument for the measurement of peak value of non-sinusoidal asymmetric voltage over wide range of frequency

This paper presents a novel approach towards measurement of peak value of high alternating voltage. Performance shows that the proposed method is suitable for laboratory applications as well as for industrial usage. The proposed scheme is low-cost and also portable and small enough to be mounted anywhere. It can be adjusted to adapt to wide range of values of high voltage arm of capacitive potential divider present at the working place for peak value measurement. The peak voltmeter (PVM) circuit is tested with the help of different waveshapes at different frequencies and the results show that it can measure the peak values for a wide spectrum (from 50 Hz to 1 kHz) of waveforms efficiently.
