Abstract

This paper proposes a stator turn-to-turn fault detection for inverter-fed electric machines using the voltage difference between two neutral points (NP's). By designing machine Y-connected windings with a secondary neutral point (NP), a voltage difference between two NP's appears once a turn fault occurs. Because this fault signal is induced by the voltage… (More)
