Abstract

PURPOSE:To decide exactly whether an abnormality exists or not by deciding that the abnormality exists when the difference of an apparent power calculated from effective and reactive powers detected in a system, and an apparent power calculated from a voltage detected in the same way exceeds a prescribed value. CONSTITUTION:An apparent power PL is derived by an expression from the respective differences P3=P1-P2, Q3=Q1-Q2 of an effective power P1, and a reactive power Q1 flowing into a terminal T1 of an electric power equipment having an impedance R+jX, and an effective power P2 and a reactive power Q2 flowing out of a terminal T2. Also, a loss PV=(V1-V2)I1 is derived from voltages V1, V2 and a current I1 of the terminals T1, T2. Moreover, a difference of losses derived from a calculation of two kinds, P0=¦PL-PV¦ goes to zero ideally, therefore, when the difference P0 of losses exceeds a range prescribed in advance, it is decided that the equipment is abnormal.
