Sizing Guide
When is 1000 kVA the right choice?
1000 kVA is a plant-level rating, not a machine-level rating. It is typically specified when an entire factory block — compressors, heavy presses, conveyors, paint booths, and office loads — feeds from a single HT/LT transformer and the facility engineer wants a single point of voltage regulation before the main LT bus. At this size, dual servo motor control is essential: a single servo mechanism cannot physically respond fast enough across a full 1000 kVA window. Petrochemical process plants and semiconductor fabs also specify this rating because their equipment cannot tolerate even transient voltage events during critical batch cycles. SCADA integration is standard on this unit — your control room will see the stabilizer's input voltage, output voltage, load percentage, and fault log in real time.
