then confirm the scope.

Review full ratings, winding connections, impedance, tap configuration and physical interfaces with your project engineer. Request serial-specific photographs, nameplates, available tests and an accessory list before confirming suitability.

New/unused, pre-owned and rebuilt describe different histories. Storage, service, repairs and warranty need their own documentary review.

Plan the purchase

Ask for current quantity, authorized location, release conditions and a quotation identifying equipment, preparation, freight, oil handling, offloading and installation responsibilities. Unknown records or dates require confirmation.
