Abstract
There is provided a method of locating a fault in a power transmission medium, including: monitoring, at a first monitoring location, an electrical characteristic of a power transmission medium at a plurality of frequencies; detecting, at the first monitoring location, a set of propagating fault signals including: a first propagating fault signal of the electrical characteristic at a first frequency of the plurality of frequencies, and a second propagating fault signal of the electrical characteristic at a second frequency of the plurality of frequencies, wherein each propagating fault signal is caused by the fault in the power transmission medium; comparing the first and second propagating fault signals with one another to obtain a set comparison value; and determining a location of the fault in the power transmission medium by deriving, from the set comparison value, a fault distance from the first monitoring location.
