Description

3-Phase 200 kVA Distribution Transformer:

Key Specifications and Features

1. Power Rating:
   • 200 kVA (Kilovolt-Amps): This is the transformer’s capacity to handle power. A 200 kVA transformer can deliver a maximum of 200,000 volt-amperes to the load, suitable for medium-scale applications.
2. Phase Type:
   • 3-Phase: The transformer operates on three-phase electrical systems, which are commonly used in commercial, industrial, and large-scale residential distribution networks for better load balancing and efficiency.
3. Cooling Method:
   • Oil-Immersed Type: Most 200 kVA transformers use mineral oil (or synthetic oil) for cooling and insulation. The oil circulates inside the tank, dissipating heat generated during operation.
   • Radiators: Oil-immersed transformers often have radiators or fins on the tank to facilitate heat dissipation.
4. Core and Windings:
   • Core Material: Typically made from laminated silicon steel to minimize losses due to eddy currents and hysteresis.
   • Windings: The transformer has copper or aluminum windings for the primary and secondary coils. Copper is more efficient but is more costly, while aluminum is less expensive but may have higher resistance.
