【Abstract】 Based on distributed parameter circuit theory and modal analysis theory,a number of new algorithms of line to line,single line to ground & double line to ground fault location for (a)symmetric ungrounded 3 phase system are proposed in accordance with the characteristic of the system.Simulation of fault location by computer and tests on the fault model simulation lines show that the algorithms presented in the paper are effective.更多还原
