SPLIT PHASE
Some generators, due to physical construction, have windings that consist of multiple adjacent turns. It is therefore possible
for faults to develop between turns on the same phase (inter-turn faults). These faults are not detected by the stator differ-
ential protection, as there is no difference between the neutral and at the terminal currents. Split phase protection may be
applied to detect inter-turn faults in the case that the generator is wound with two three-phase windings, each brought sep-
arately out of the machine and connected in parallel. The currents in the two windings are compared, any difference indicat-
ing an inter-turn fault.
