为了更好地了解雷电对配电线路的干扰影响，描述了一个独特的项目，该项目涉及建造一条10公里的测试配电线路以及一个自动雷电和浪涌记录站。初步数据进行了两个完整的雷暴季节的测量，在直接中风的线路和感应过电压浪涌特性。大多数雷电干扰是由附近对地放电的感应引起的，具有正极性，很少超过100 kV，并且通常根据经典的电磁场感应理论来解释。也获得了几个双极浪涌记录，然而，其特性偏离理论预测很大，它被认为这可能是由于领导机构的影响。它还发现，直接中风的发病率线是远远大于传统理论的预期，也是多极闪络的频率，它的结论是，需要进一步研究的吸引力的影响线和罢工过程的最后阶段。
In an attempt to arrive at an improved understanding of the disturbing influence of lightning upon power distribution lines, a unique project is described involving the construction of a 10km test distribution line together with an automated lightning and surge recording station. Preliminary data are presented from measurements carried out over two full thunderstorm seasons, in respect of direct strokes to the line and induced overvoltage surge characteristics. The majority of lightning disturbances are caused by induction from nearby discharges to ground, are of positive polarity, rarely exceed 100 kV, and are generally accountable in terms of classic electromagnetic field theories of induction. Several bipolar surge records have also been obtained, however, whose characteristics deviate considerably from theoretical prediction, and it is considered that this might be due to the influence of the leader mechanism. It is also found that the direct stroke incidence to the line is considerably greater than anticipated from traditional theory, as is also the frequency of multiple pole flashovers, and it is concluded that further research is required on the attractive effects of lines and of the final stages of the striking process.
