Sizing Guide
When is 500 kVA the right choice?
500 kVA is the standard rating for large integrated manufacturing floors — think a 15,000 sq ft plastics injection plant running 8–10 machines simultaneously, or a textile mill with multiple rapier looms, humidifiers, and overhead cranes on the same feeder. At this scale, a relay-type stabilizer or static AVR cannot keep up with the rate of load change; servo motor technology is the only reliable option. The 500 kVA unit also serves as the incomer stabilizer for multi-tenant industrial estates where the landlord wants to provide clean power to all tenants from a single point. Oil cooling is standard at this rating — the heat dissipation from a 500 kVA unit in continuous duty exceeds what any air-cooled enclosure can manage reliably.
