## Appendix A  
The appendix presents the FRA measurement for the 5.5 HP IM phase-to-neutral (U-N) which could support the findings from the other U-V measurement. The used FRA measurement in the main content is for the phase-to-phase measurement which can show more details on the traces variation compare to phase measurement configuration. * _[PERSON] et al.
