Thank you for sharing your knowledge; I see some doing motor starting analysis in Transient stability module? why?

One Problem, for Dynamic, we shall input Moment of inertia WR2 ( kg m2). How to calculate Moment Inertia WR2 (kg-m2) in ETAP? Is there any standard to calculate WR2?. I found in IEC 60034-12, Table 4. External Moment of Inertia J ( kg m2) for each kW of motor. Is it same WR2 and J?
J in IEC 60034-12. Mentioned as J=0.04P^0.9xp^2.5

Firstly, I want to express my gratitude for providing such a valuable video on the subject. It has been very helpful for my studies. However, I do have a question, and I was wondering if you could assist me with it.
I am working on a similar system and need more detailed guidance on how to model the MV VFD (Medium Voltage Variable Frequency Drive) during the start Dev section. Specifically, my question is regarding the selection of the appropriate V/hz (Voltage-to-Frequency) ratio for an MV system operating at 5.5 KV, as opposed to a Low Voltage system.
Additionally, I am looking to run my motor at 65 Hz, and I am unsure about how to accurately simulate this in my study.
I would be extremely grateful for any insights or advice you could provide on these matters. Thank you once again for your valuable contribution through your video.
Best regards,
