| Abstract: | Leading negative impedance into circuit of electric meter, the systematic errors are eliminated, thus, the no internal impedance electric meter is designed. In this paper, the measurement errors caused by internal impedance are analyzed, the method of eliminating internal impedance using negative impedance is introduced, and the principle circuit of negative impedance and application circuit are given. |
