每当雷电或倒树造成电线断路或短路时,就必须用信号通知电站更改故障周围的电力输送。但由于传送继电器自动跳闸和重新安排负载信号的通信线路沿着高压线布设,电磁干扰偶尔会产生虚假信号。为避免这些问题,美国、加拿大、英国以及其它国家的电力公司正转向光纤通信,这种通信具有抗干扰能力。据马里兰州杰曼顿M/A-Com DCC(前数字通信公司)光波通信分公司国内推销经理沃尔特[R.D.(Bob)Wolter]透露,远离纽约经营的尼亚加拉
Whenever a lightning or down tree causes a wire break or short, it must signal the power station to change the power transfer around the fault. However, due to the automatic relay relay relay and rearrange the load signal communication lines along the high-voltage line layout, electromagnetic interference occasionally produce false signals. To avoid these problems, the power companies in the United States, Canada, the United Kingdom and other countries are turning to optical fiber communications, which have anti-interference capabilities. According to R.D. (Bob) Wolter, domestic sales manager at M-A-Com DCC (formerly Digital Communications) Lightwave Communications in Gemanmanda, Md., Niagara,
