I ran across a voltage i'm not familiar with actually seeing in a commercial building in the Portland area. We installed some step down transformers for a power vent upgrade 208/230 primary-120 secondary.When checking the voltage the reading was 232-233-230 volt the strange thing is that all the buildings in the area are 208 volt 3 phase. Has anyone seen this before ?
