    • A fault locator of a parallel transmission line includes a data receiving unit that receives the transmission and the received signal of each current differential relay provided with the transmission line, and measures the receiving timing of the transmission signal from a self-terminal. A fault detecting unit judges fault detection on the transmission line based on current data received with the data receiving unit, and outputs a starting signal. A data memory unit stores a predetermined fault generating range of a quantity of electric data of each self-terminal previously stored and an other side terminal when the quantity of electric data of each self terminal received with the data receiving unit and the other side terminal are stored and a starting signal is received. A synchronous correction unit, based on information on the receiving timing measured with the data receiving unit at the time of data reception of a self-terminal transmission signal, performs synchronous correction processing between each line to the stored memory. A setting unit inputs an impedance value and the line-length for three-phases as a setting value. A fault location unit performs fault location, using impedance setting for three-phases and line-length setting which were set with the stored memory data and the setting unit and the synchronous correction processing between each line that was performed in the synchronous correction unit.
    • 并行传输线的故障定位器包括:数据接收单元,接收传输线路的每个电流差动继电器的发送和接收信号,并测量来自自身终端的发送信号的接收定时。 故障检测单元根据与数据接收单元接收的当前数据判断传输线上的故障检测,并输出启动信号。 数据存储单元存储当与数据接收单元和另一侧端子接收的每个自身终端的电数据数量是在以前存储的每个自身终端的电数据量的预定故障产生范围和另一侧终端时 存储并接收起始信号。 基于在数据接收单元在自身终端发送信号的数据接收时测量的接收定时的信息的同步校正单元在存储的存储器之间的每一行之间执行同步校正处理。 设置单元输入三相的阻抗值和线路长度作为设定值。 故障定位单元使用由存储的存储器数据和设置单元设置的三相和线路长度设置的阻抗设置执行故障定位,并且在同步校正单元中执行的每条线之间进行同步校正处理。
