14 Things About Distribution Transformers :


1. Distribution transformers are generally used for distribution of electrical energy.

2. They operates at low voltage as less than 33KV in industrial purpose and 440 to 220 Volt in domestic purpose.

3. Distribution transformers generally works at low efficiency at 50 to 70 %.

4. One of the greatest advantage is, it has small size and easy to install.

5. "Distribution transformers" has low magnetic losses. this type of transformer is not always fully loaded.

6. In Distribution transformers, core and windings are active parts. Other side, tank, cooling liquid, fans, protection devices etc.. are passive parts of Distribution transformer.

7. During manufacturing of Distribution transformers, we generally consider low reluctance, higher reliability, lowering material cost, reduction in iron loss and magnetizing current.

8. Generally we use Alloy steel with main content silicon and carbon, as a basic material of Distribution transformer. This material increases permeability and reduces losses.

9. hysteresis loss in Distribution transformers are totally depends on its core materials.

10. In Distribution transformers, the High Voltage winding is wound directly on the low voltage winding.

11. In Distribution transformers, Generally Low voltage windings are usually made of copper. Stripe paper is used to insulate the conductor.

12. In Distribution transformers, number of turns varies on KVA rating.

13. In Distribution transformers, Generally heat is produced through windings.

14. Continuity test, ratio test, magnetizing test, no load current test and short circuit tests are performed for quality control test of Distribution transformers.
