BIS CERTIFICATION FOR OIL IMMERSED DISTRIBUTION TRANSFORMERS IS 1180 (PART 1):2014

Introduction

Oil-immersed distribution transformers are vital electrical devices used to control the voltage of electricity in power distribution systems. These transformers are designed to step down high-voltage electricity received from power generation or transmission lines to lower, usable voltages suitable for local distribution. They are called "oil-immersed" because they are filled with transformer oil, a specially formulated insulating and cooling liquid that surrounds the transformer's core and windings. The main components of an oil-immersed distribution transformer include the core, primary and secondary windings, and the oil-filled tank.

The core, typically made of laminated steel, provides a magnetic path for the efficient transfer of energy. The primary winding receives high-voltage electricity, while the secondary winding delivers lower-voltage electricity to consumers. The transformer's tank is hermetically sealed to prevent moisture ingress and filled with transformer oil. This oil serves multiple critical functions: it insulates the windings, dissipates heat generated during operation, and provides a medium for cooling.

This standard, IS 1180 (Part 1):2014, pertains to outdoor type oil-immersed distribution transformers. It specifically covers naturally air-cooled, three-phase, double-wound non-sealed type transformers. Transformers within the scope have ratings up to and including 2500 kVA. These transformers are designed for use on systems with nominal system voltages up to and including 33 KV. Part 2 of IS 1180:2014 addresses sealed type outdoor distribution transformers with similar voltage and KVA ratings.
