WebApr 9, 2015 · The high resistance coil of the potential relay operates on counter electromotive force (CEMF) generated in the start winding. During the start-up period the CEMF is insufficient to operate the relay. The CEMF generated across the start winding causes a small current to flow in the start winding and through the potential relay coil.
