People Electric · Load-Adjustable Oil-Immersed Transformer
Product overview
People Electric S11-M-ZT is a three-phase sealed transformer with large- and small-capacity operating states. The manufacturer describes automatic capacity adjustment under load according to operating conditions, using a matched transformer, capacity-adjusting switch and controller. The documented capacity pairs must remain together; they are not freely interchangeable large and small ratings.
Technical selection summary

| Vector groups listed | Dyn11 or Yyn0; confirm the supplied winding and terminal connection |
| Controller / switching system | Matched transformer, on-load capacity-adjusting switch and controller; exact devices, settings and protection require project approval |
| Performance entries | The source provides paired loss/current and short-circuit-impedance entries for capacity states. Confirm units, test conditions and contractual guarantees in the factory technical schedule. |
| Monitoring features described | Power saving control, remote communication/monitoring and protection functions; confirm the exact delivered controller interfaces and service scope |
| Economic examples | Manufacturer comparison calculations use assumed duties and tariffs. No universal energy-saving percentage, payback or operating-cost guarantee is asserted. |
| Outline / supply scope | Original reference drawings are included; final dimensions, accessories, control supply, cooling and installation requirements must be confirmed for the exact paired-capacity design. |
Choose one complete documented capacity pair. The small-capacity figure belongs to that exact large-capacity version, and capacity switching requires the matched controller and switch. Confirm system frequency, transformer/relay protection, capacity-change conditions, performance guarantees and site requirements before ordering. The complete original PDF remains unchanged.
Typical applications
- Distribution systems with substantially changing load demand.
- Project-engineered rural, agricultural or industrial distribution transformer installations requiring controlled capacity switching.
