As the German industrial norm VDE 0100 prescribed the phase sequence for all types of three-phase connectors in a way incompatible with the original Perilex pinout, the R and T connectors may have been swapped.

For two electrical systems to be synchronized, both systems must operate at the same frequency, and the phase angle between the systems must be zero ( and two polyphase systems must have the same phase sequence ).

Studying the phase behavior of polystyrene-block-polyisoprene in solvents of varying selectivity, the concept of phase trajectories was introduced to explain the phase sequences observed as a function of concentration in neutral and selective solvents connecting the solution behavior to that seen in block copolymer melts.
