    • A method of locating a fault point in a parallel two-circuit transmission line in an n-terminal system. When a single fault occurs at one place in one circuit of the transmission line and when a multiple fault occurs at the same place in the two circuits, a distance to the fault may be calculated by the method of this invention. The method comprises the steps of transforming the transmission line into a T three-terminal parallel two-circuit transmission line circuit having three branches, calculating a value representing a length of one of the three branches on the basis of differential currents flowing into the branch points of the transmission line, determining if that value represents the distance from a terminal connected to the branch point to the fault point, employing the value as the distance to the fault point if the value represents such a distance, repeating the value calculation and determination for the other two branches if the value does not represent the distance to the fault, determining a next branch point for which to perform equivalent transformation with respect to, and repeating the previous steps until the fault is found.
    • 一种在n端系统中的并联双回路传输线中的故障点的定位方法。 当单个故障发生在传输线路的一个电路中的一个位置,并且当在两个电路中的相同位置发生多个故障时,可以通过本发明的方法来计算到故障的距离。 该方法包括以下步骤:将传输线变换成具有三个分支的T三端并行两电路传输线电路,根据流入分支点的差分电流计算表示三个分支之一的长度的值 确定该值是否表示从连接到分支点的终端到故障点的距离,如果该值表示该距离,则将该值用作到故障点的距离,重复该值计算和确定 其他两个分支如果该值不代表与该故障的距离,则确定相对于其执行等效变换的下一分支点,并且重复前述步骤直到发现故障。

    • A reception data expander includes: an adaptive differential pulse code modulation (ADPCM) decoder activated when error detection information attains a reception data error nondetected state for expanding an input ADPCM code into a PCM (pulse code modulation) code, and inhibited of its decoding process operation when the error detection information indicates an error detected state; a memory circuit set to a write state when the error detection information attains an error nondetected state for sequentially storing generated ADPCM code, and outputting a stored PCM code when the error detection information is rendered to an error detected state; and a reconstructed output switch for selecting and providing to the next PCM decoder a PCM code when the error detection information attains an error nondetected state, and a PCM code read out from the memory circuit when the error detection information attains an error detected state. Noise generation arising from discontinuity of an ADPCM code at the time of reception data generation can be suppressed effectively without increasing the device complexity and power consumption.
