What is Single Phasing about?

If a fuse blows on a 4.16kv system what will be some of the other adverse effects that would occur besides single phasing? Obviously smaller 3-phase 120 / 208 transformers would be effected as well. The voltage on two secondary phases will be 50% of nominal and will be in phase, not 120deg out of phase. The open primary bushing will have a voltage halfway between the two intact phases. This is if there is no load. Connected motors may change
