In 1918 Charles Legeyt Fortescue presented a paper which demonstrated that any set of N unbalanced phasors (that is, any such polyphase signal) could be expressed as the sum of N symmetrical sets of balanced phasors, for values of N that are prime. Only a single frequency component is represented by the phasors.

Webto a bipole option, is loss of redundancy with a permanent line or cable fault. For a single pole-to-ground fault for the ungrounded symmetrical monopole of Figure 1, no power transfer is lost during the fault since load current still flows and pole-to-pole voltage stays the same, while the voltage of the un-faulted pole jumps to two per-unit.
