"A dominant faulting phase is a strong indication of bird streamer related faulting. Bird streamer
related faults tend to be prevalent on the phase which is situated below the highest and/or
most convenient perching space on the tower. On vertically configured designs, this usually
results in the top phase (or phases in the case of double circuit towers) faulting disproportionately to
the other phases , as the birds tend to roost on the highest cross-arm. With horizontally configured
designs, the middle phase is usually the dominant faulting phase. In South Africa, the middle phase on
275kV self-supporting towers is the dominant bird streamer related faulting phase due to the tower
design which makes is difficult for birds to roost above the outside phases."
