In this paper, a method of measuring the input mechanical impedance of the array element (longitudinal vibrating transducer) with square radiation head by using impulse sound tube is proposed.
本文提出了以声脉冲管测量辐射头为方形的一种阵元(纵向振动换能器)的输入力阻抗的方法。

The analysis shows that the measured impedance at the head of the line is not proportional to the fault distance when a three-phase fault occurs at the end of the line.
分析表明，线路末端三相故障时，线路首端的测量阻抗不与故障距离成正比。
