FAQ

1. What is an oil immersed transformer and how does it work?

An oil immersed transformer uses insulating oil for cooling and dielectric protection. The oil absorbs heat from the windings and releases it through the tank’s cooling structure.

2. What are the key components of an S11 oil type transformer?

Core components include the corrugated tank, pressure relief valve, oil level gauge, thermometer, earthing bolt, nameplate, and dual-purpose valve for oil filtration.

3. How do I check the oil level and temperature in a three phase transformer?

You can monitor both through the integrated oil level gauge and precision thermometer installed on the transformer tank.

4. What maintenance is required for oil type distribution transformers?

Main tasks include checking insulating oil quality, monitoring temperature, inspecting seals, and ensuring cooling fins stay clean for proper heat dissipation.

5. How does the corrugated cooling tank improve transformer performance?

The corrugated structure increases surface area, boosting heat dissipation efficiency and extending the life of the transformer insulating oil.

6. What applications are suitable for S11 50/100kVA transformers?

Typical uses include commercial buildings, rural distribution networks, industrial loads, solar PV systems, and compact substations.
