    • Provided is a sensor for measuring electrical characteristics. The sensor includes a printed circuit board defining a round through-hole into which a power transmission line is inserted; a voltage sensor including a ring-shaped electrode and a first terminal portion to measure a voltage formed in the power transmission line, the electrode being fixed against the inner periphery of the through-hole to measure a voltage formed in the power transmission line, and the first terminal portion having one end in contact with one side of the electrode and the other end exposed through one side of the printed circuit board; and a current sensor including a pickup coil and a second terminal portion to measure current flowing in the transmission line.
    • 提供了一种用于测量电气特性的传感器。 该传感器包括限定了输入电力线被插入的圆形通孔的印刷电路板; 电压传感器,包括环形电极和第一端子部分,用于测量在输电线路中形成的电压,电极固定在通孔的内周,以测量在输电线路中形成的电压;以及 所述第一端子部分的一端与所述电极的一侧接触,另一端暴露于所述印刷电路板的一侧; 以及电流传感器,其包括拾波线圈和第二端子部,以测量在所述传输线路中流动的电流。
