Interpretasi Praktis Terhadap Istilah-Istilah Daya pada Rangkaian Listrik Satu Fase Sinusoidal

Abstract

In electrical engineering, there are several power terms; active power, reactive power, instantaneous active power, instantaneous active power, instantaneous power, apparent power and complex power. Even though are used in daily activity, electrical practitioners are facing difficulty to explain those terms practically. This paper tries to solve those difficulty by interpret those term in practical way. Firstly, each power term are defined theoretically. Then those terms are presented mathematically. Next, power in single phase sinusoidal electric network is analyzed. Theoretical definition result is connected with power analysis result. Computer simulations are held to strengthen interpretation result. Considering the width of discussion area, this paper only covers most general application, that is single phase sinusoidal network.
