Fault analysis on AC/HV cable transmission lines

The subject of this paper is the analysis of the behavior of an ac/HV (400 kV) cable line, compensated with shunted inductors, in the event of a fault. Comparisons are made between, and the consequences assessed for a three-phase, single and double phase-to-ground short circuit, starting fromvarious operating conditions. The paper presents criteria applied for assessing the worst fault and the influence of compensating parameters under fault conditions, and for locating the most severe type of fault.
