Abstract
The paper presents a method to measure the parameters of four circuits AC lines on the same tower. At first, the positive sequence open circuit impedance and short circuit impedance are both measured for any one of four lines. Secondly, four cases of 2-phase systems are assembled by four lines on the same tower, and then the open circuit impedance and short circuit impedance of 2-phase systems are measured for each case. Based on open circuit impedance and short circuit impedance measurements above, the distributed impedance and admittance for each case are accordingly estimated. Finally, the mutual inductance and coupling capacitance, as well as self-parameters of each line can be calculated.
