Electrical and Electronics Measurements: Power and Energy Methods

Accurate measurement is the cornerstone of electrical engineering, yet calculating power and calibrating energy meters can be challenging without a solid grasp of foundational circuit behavior. This course provides a clear, text-based breakdown of the mathematical and physical principles behind electrical instrumentation. You will transition from basic theory to confidently analyzing complex measurement setups used in modern industrial and utility systems. What you'll learn: - Understand the core principles of Blondel's Theorem and how to apply it to multi-phase systems - Analyze the two-wattmeter method to calculate active power, reactive power, and the overall power factor - Identify and calculate systematic errors arising from MC and LC connection configurations - Evaluate the impact of potential coil inductance on measurement accuracy - Examine the construction, working principles, and common errors of induction-type energy meters - Apply compensation techniques for creeping errors, friction, and phantom loading scenarios - Explore modern digital metering trends and smart grid integration fundamentals This course begins with essential terminology, basic circuit laws, and foundational measurement concepts before diving into advanced power and energy formulas. You will progress systematically from single-phase power calculations to polyphase systems and meter calibration techniques, supported by clear written examples and practical troubleshooting scenarios. This course is designed for beginner electrical engineering students, technicians, and power system enthusiasts who want to master measurement principles without requiring advanced prerequisites.
