Budget estimate for a 6.6 KV, 1000 KW VFD 1

[edison123]

Looking for a budget estimate for a 6.6 KV, 1000 KW air cooled VFD with and without sinusoidal filter and approximate footprint for each.

Any ideas, drive gurus?

I can't speak for pricing in India, but here, roughly $150k for a CHB format VSI 36 pulse drive, without a DV/DT filter, but good for 800m from drive to motor, standard motor windings. No idea on the cost of adding an output filter, those are one-off quoted, but figure another 1000mm W cabinet. Physical size of the basic drive and transformer would be 4520mm W x 1362mm D x 2648mm H, 5570kg

That was for a Rockwell drive, looking at Siemens, ABB and TMEIC, they are all similar dimensions for that power and voltage.

Thanks, Jeff. Why the transformer?

800 meters cable between VFD and the motor without dv/dt filter? I thought the limit was around 200 meters.
