| Pole-Mounted | Installed on utility poles for rural or urban distribution |
| Pad-Mounted | Used in ground-level power distribution cabinets |
Frequently Asked Questions (FAQ)
Q1: Can a 15 kVA transformer handle household loads?
Yes, a 15 kVA single phase transformer is ideal for residential applications such as air conditioners, lighting, refrigerators, and small tools.
Q2: What’s the typical efficiency of a 15 kVA transformer?
Most single phase transformers in this range offer 95% to 98% efficiency, depending on the load and design.
Q3: How do I choose between oil-immersed and dry-type?
If your transformer is installed outdoors, an oil-immersed model is usually better. For indoor environments, a dry-type unit is safer and cleaner.
