BIS for Distribution Transformers: A Simple Guide to Safe and Trusted Power Supply

Electricity is a basic need in our daily lives. To carry electricity safely from power stations to homes and offices, we use machines called distribution transformers. These transformers must be safe and follow the rules set by the government. That’s where BIS for Distribution Transformers comes in.

The Bureau of Indian Standards (BIS) makes sure that every transformer meets safety and quality rules. In this blog, we will help you understand why BIS is needed, how it works, and how a BIS consultant helps manufacturers in the process.

IS 1180: The Standard for Safe and Efficient Transformers

IS 1180 is the Indian Standard code for liquid-immersed distribution transformers. It helps make sure that the transformer works safely, lasts long, and saves energy.

This standard covers the design, testing, and performance of transformers up to 2500 kVA. It also includes important rules about the cooling system, energy loss, and safety parts.

IS 1180 is important because:

• It ensures transformers are safe to use for both people and equipment.

• It helps reduce the power loss during electricity distribution.

• It supports the Make in India movement by improving product quality.

• It helps in saving electricity and protects the environment.

Without this standard, unsafe transformers may damage wires, cause power cuts, or even catch fire.
