Empower Your Transformers – Get BIS Certified with Confidence

In today’s competitive electrical equipment market, quality, safety, and regulatory compliance are non-negotiable. When it comes to distribution transformers—both indoor and outdoor liquid-immersed types—ensuring BIS for Transformers certification is more than a legal formality. It’s a commitment to performance, reliability, and safety. That’s where EVTL India comes in. With in-depth knowledge of IS 1180 Part-3 standards and a proven track record of certification success, EVTL India empowers your transformers to meet BIS norms with confidence and ease.

Why BIS Certification for Distribution Transformers?

BIS certification under IS 1180 (Part-3) is mandatory for all outdoor and indoor liquid-immersed distribution transformers manufactured or imported in India. This standard ensures that the transformers meet specific performance, safety, energy efficiency, and durability requirements. The goal is to safeguard power distribution systems from substandard equipment and promote long-lasting, energy-efficient transformer usage across the nation. Whether you are a domestic manufacturer or an international importer, obtaining BIS certification demonstrates that your product adheres to Indian safety and quality benchmarks, making it a necessary credential for market entry and trust.

What is IS 1180 Part-3?

IS 1180 is divided into multiple parts, and Part-3 specifically deals with BIS requirements for indoor and outdoor type liquid-immersed distribution transformers. It lays down stringent norms covering:

Thermal performance and overload capacity

Voltage regulation and dielectric strength

Efficiency and no-load/load loss limits

Short-circuit withstand capacity

Mechanical construction and insulation

By complying with IS 1180 Part-3, you ensure that your distribution transformer is fit for high-performance environments and long operational life.

Challenges in the BIS Certification Process

Getting BIS certification for transformers under IS 1180 (Part-3) is a detailed process. It requires:

Filing technical documentation

Undergoing rigorous product testing at BIS-recognized labs

Site inspections

Factory audits

Regular surveillance and compliance updates

The complexity of procedures and evolving regulatory updates can overwhelm manufacturers and importers. Missing a single step can delay certification or lead to rejection.
