Electric Power Systems Research, 2012 This paper develops and analyzes a methodology for detecting stator winding inter-turn faults in surface-mounted permanent magnet synchronous motors. The proposed methodology is based on monitoring the zero-sequence voltage component having into account the effects of the inverter that usually feeds the machine.

Demagnetisation fault detection in PMSM using zero sequence current components
Electronics Letters, 2017 A demagnetisation fault detection method for a delta‐connected permanent magnet synchronous machine (PMSM) based on zero sequence current components (ZSCC) is proposed. The model of the delta‐connected PMSM with the demagnetisation fault is first established.

Impact of zero sequence component on voltage-source converters
Proceedings of the Power Conversion Conference-Osaka 2002 (Cat. No.02TH8579), 2003Presently, the preferred circuit of PWM (pulse width modulation) converters has the open-wye 3-phase connection, in which the zero sequence does not exist. Single-line-to-ground fault studies have shown that the grounded-wye connection is better from protection and security consideration.

Induction machine diagnostics using zero sequence components
Fourtieth IAS Annual Meeting. Conference Record of the 2005 Industry Applications Conference, 2005., 2005Induction machine diagnostics using zero sequence components is presented in this paper. Electrical faults cause asymmetries in the phase impedances, producing a zero sequence voltage in wye-connected machines and a zero sequence current in delta-connected machines.

The control and analysis of zero sequence components in DVR system
2001 IEEE Power Engineering Society Winter Meeting. Conference Proceedings (Cat. No.01CH37194), 2002The magnitudes and phases of the compensating voltages in a dynamic voltage restorer (DVR) system depend on the voltage sag in the phases affected by the fault and on the influence of the zero sequence components. If the delta connection of the transformer is used, the zero sequence components do not appear on the load side. But nowadays, wye connected
