Introduction to Electric Power Metering: Single and Three-Phase Systems

Accurate measurement of electrical energy is the backbone of utility billing, industrial energy management, and modern grid systems. Understanding how power and energy are calculated and metered is essential for anyone entering the electrical, energy management, or utility sectors. This text-based course guides you from foundational electrical concepts to the practical application of power metering. You will develop a solid grasp of how electricity is measured, calculated, and monitored in both residential and industrial environments. What you'll learn: - Define the core concepts of electrical charge, voltage, current, power, and energy. - Calculate active, reactive, and apparent power in single-phase systems. - Understand the operational principles of three-phase electrical systems and their metering configurations. - Explain the differences between traditional electromechanical meters and modern digital smart meters. - Convert electrical quantities and calculate energy consumption patterns from meter readings. - Apply safety and industry-standard practices when evaluating metering circuits. The course begins with foundational definitions of power and energy before progressing to circuit mathematics. You will then explore the wiring, configuration, and real-world applications of single-phase and three-phase metering setups. This course is designed for beginners, aspiring electricians, energy auditors, and technicians, requiring no prior electrical engineering background.
