System for concurrent digital measurement of peak voltage and RMS voltage in high voltage system

摘要

A voltage measurement system is provided which concurrently measures peak voltage and root mean square voltage. The voltage measurement system employs a digital peak detection circuit for peak voltage measurement. The voltage measurement system employs a memory device for storing samples of a voltage signal at predetermined intervals corresponding to a line frequency multiplication factor. The samples in the memory device are then used to calculate root mean square voltage.
