You don't run 170 amps of 240v nearly 1/2 a mile. You would be talking extremely large conductors and multiple conductors per phase to limit voltage drop.

You need a different solution. A new service close to the location, a step-up and step down transformer solution, diesel power generator, diesel mechanical power in place of the electric motor, etc.

This is not even remotely a DIY job. Please call someone who knows what they are doing to do this job correctly and safely.

You have a 28HP single-phase motor? I didn't know they existed? What's it running?

The only way to effectively do this is to bring the primary (high voltage) service MUCH closer to the point of use. Even step up/step down setup is much more expensive and over complicated.

Why so far? Is this like a several hundred acre facility? Is that whole distance your property?
