This paper deals with the performance evaluation of cross-differential protection applied to double-circuit transmission lines which share the same tower, considering the occurrence of inter-circuit faults. Aiming to do so, sensitivity and transient analysis were carried out on a 300 km double-circuit transmission line with 500 kV of rating voltage, modeled on Alternative Transients Program (ATP). By the analysis of the obtained results, the cross-differential protection function is able to detect faults between two different phases of the two existent circuits and has a high instantaneous coverage for such type of fault.
