Abstract Based on the assumption of the three-phase AC impedance parameters unbalanced and the electromagnetic induction voltage invariant in a short time, a new measurement method of the power frequency impedance parameters of double-circuit transmission lines on same tower is proposed. The new measurement method applied a single-phase power frequency power connected to the transmission lines by different ways,and obtained the sequence impedances and sequence coupled impedances of single-circuit or double-circuit transmission lines by establishing the mathematics model,fitting the experimental data,transforming the matrix. This method overcomes the influence of the induction voltage and three-phase unbalanced problem, and it is simple, accurate and stable etc. The measurement results show the validity of this method.

Key words： Double-circuit transmission lines on same tower three-phase AC impedance parameters unbalanced the power frequency impedance parameters measurement method
