Multi-terminal network power measurement

This paper presents a simple and general theory on power absorbed by multi-terminal networks and the way to measure it, which has direct application to unification of active and reactive power measurement procedures of polyphase loads. This approach to the subject is highly efficient, not only for its simplicity, but also because it eliminates all particular demonstrations or proofs of different measurement methods, with consequent time and effort savings for students. It also offers absolute certainty about the scope of every power measurement procedure and their possible variations.
