What is a Distribution Transformer?
A distribution transformer is an electrical device that reduces high-voltage electricity from the distribution network into lower voltages suitable for homes, offices, industries, and commercial establishments.
These transformers are generally installed near the end users and operate continuously throughout the day. Since they remain energized for long periods, they are designed to provide excellent efficiency with minimum power loss.
Distribution transformers are available in different capacities to meet varying power requirements.
Some commonly used ratings include:
- 25 kVA
- 63 kVA
- 100 kVA
- 160 kVA
- 200 kVA
- 250 kVA
- 315 kVA
- 500 kVA
- 630 kVA
- 1000 kVA
Each transformer is designed for specific load conditions depending on the electricity demand.
