Abstract
The present disclosure relates to detecting a broken conductor in a power transmission line. In an embodiment, a processor receives a signal indicating current on the transmission line. The processor determines that a broken conductor is present on the transmission line based at least in part on a magnitude of the current being less than a line charging current of the transmission line and a phase angle of the current leading a respective phase voltage of the transmission line. The processor effects a control operation based on the determined broken conductor.
