ANovel Method for theMeasurementofPower, Power Factor, rms, and Average Values of Voltage and Current of Distorted Power Frequency Waves

This paper presents a novel statistical approach to the measurement of power, power factor, rms, and average values of voltage and current in distorted power frequency waves. Utilizing a time-division technique, the methodology transforms input voltage and current signals into two normalized binary signals that convey information about their shapes and phases. By applying these signals through an EXCLUSIVE-OR gate, a binary signal is generated, facilitating the extraction of power factor as either a DC voltage or digital data. The instrument demonstrated versatility in measuring average voltage, true rms values, power, energy, and related ratios. Experimental results derived from a constructed laboratory model confirmed the theoretical framework, showcasing effective measurement capabilities even with distorted wave forms at a fundamental frequency of 50 Hz. The approach emphasizes the benefits of simplified electronic circuitry to calculate commonly required engineering quantities, positing its potential for high-precision power and energy measurement applications. The findings indicate that this method can provide accurate and stable measurements, expanding the possibilities within electronic instrumentation in power engineering.
