315kVA 13.2kV Three Phase SCB series Dry Type Transformer dimensions and weight details

Frequently asked questions (FAQ)

Q: What is the load capacity of a 25 kVA transformer in kW?

A: Power Rating – The 25 kVA rating means the transformer can supply around 20-25 kW of active power. This depends on the load power factor. The amperage capacity is typically in the 60-100A range on the secondary side.

Q: Which is better, an oil type or dry type transformer?

A: Oil-immersed transformers are more efficient than dry-type transformers, which are larger and have lower voltage ratings. As a result, dry-type transformers are more likely to overheat when overloaded, leading to higher power losses and maintenance costs.

Q: How to size a transformer kVA?

A: The calculation for transformer size in a delta-connected system involves determining the KVA of the individual phase with the largest total load and multiplying that number by three. This ensures each phase can handle its specific load, preventing under-sizing issues from a simplistic total load calculation

Q: Why transformer is so expensive?

A: This is because larger transformers require more materials and components, such as larger cores, more windings and more insulation. In addition, the manufacturing process for larger transformers can be more complex and time-consuming, leading to higher labour costs.
