Q1. What is a sinusoidal peak voltage meter?
Answer: This voltage meter reads the peak value of the sinusoidal voltage which we use in our all applications of daily life. All the meter available commercially and used in the different applications, read the root mean square value of the sinusoidal voltage which is obtained from the average value of the sinusoidal voltage.
Q2. How does the sinusoidal RMS voltage meter works?
Answer: Measurement of any quantity is very important. All the commercially available voltage meters, measures the Root Mean Square (RMS) value of the sinusoidal voltage. This RMS value is obtained from the average value of sinusoidal voltage during one cycle. As the average value of sinusoidal voltage during one cycle is zero, so using the rectifier circuit, the negative half cycle is converted into positive cycle and average value is calculated for one cycle.But the indicated/displayed voltage on the scale of meter will be the RMS value of the waveform. This RMS value of voltage is obtained from the average value of the waveform. So voltage meter is calibrated to display the RMS value from the average value.
Q3. How do the peak value and RMS values of a sinusoidal voltage are related?
Answer: The RMS value for a sine wave is approximately .707 times the peak value.
Q4. What is the importance of peak voltage of sinusoidal voltage?
Answer: The value of peak voltage of a sinusoidal signal is very important. The breakdown of insulation and failure of power supply cable is dependent on the peak value of the applied voltage and not on the effective value. So measurement of the peak value is of immense importance.
Q5. How the patented circuit does differ from the existing methods?
Answer: The patented circuit for measurement of peak value of sinusoidal voltage directly. It does not measure any average or RMS value but directly reads the peak value of the voltage. Its response is fast in compare to other available circuits.
