摘要：

The basis of a new ultra-high-speed transmission-line protection scheme is described. Analog processing is performed using charge-coupled devices to extract the fault or superimposed components impress on a power system following a disturbance. The new arrangement is designed for use in conjunction with carrier blocking communication equipment and tripping times of typically 2 to 4 ms are shown to be feasible for most faults. The results of laboratory tests are given.
