| Abstract | ||||
| The waveshapes and magnitudes of overvoltages produced by the energisation of cable/line transmission systems depend on the relative position of the cable and the overhead line with respect to the energising source as well as, on the value of the source inductance. The effects of these two factors are investigated using a computer program on a three-phase basis. Under some circumstances, the overvoltages produced may be far more severe than those produced in transmission circuits consisting of overhead lines alone. The use of shunt-reactive compensation has proved to be advantageous, particularly in these cases where a cable/line system is being energised from a highly-inductive source. Moreover, it is found that the reduction in overvoltages is further increased for the same compensation value, when shunt reactors are distributed at both ends of the transmission system than when they are concentrated at one end only. | ||||
