Why Choose Copper
The advantages of using Copper in transformer windings:
- Inherent low loss material
- Special skills not needed during jointing and termination (significant percentage of transformer failure can be attributed to defective joints and termination)
- Copper scores over Aluminium in several respects such as conductivity, resistance, thermal conductivity, better withstanding capability during short circuit, etc.
- Easy availability and competitive pricing favours “Copper” usage.
Transforming the Transformer
Distribution Transformers (DTs) are key assets for any distribution network. Their reliable and efficient operation can result in long-term benefits for the Indian power distribution utilities. The DT failure rate in India is high in the order of 12-15% (in State Utilities), as against global average of less than 1%. Active repair is preferred over Reactive methods to significantly reduce the technical losses in DT and improve reliability.
- Reduces technical losses, thereby saving power procurement costs
- Allows for further improvement in energy efficiency of transformers as mandated by BEE in PAT-2 cycle
- Improves transformer reliability, thereby reducing downtime
- Increases kVA capacity of the transformer
- Creates an opportunity for the DT OEM or repairer to become a stakeholder in network O&M
Economic impact of DT failure in India
Active repair of DT
A pilot study was also undertaken We have undertaken pilot study on a 100 kVA & 200kVA DT at a public and private DISCOM respectively implementing the Active Repair solution.
Results for both pilots are in the white paper.
What We Do
International Copper Association India has taken up this project to improve the situation by advocating better technological options (Reliable and Efficient distribution transformers) to reduce failure rates and improve on losses. ICA India is promoting the use of low-loss, high-grade materials for the core and winding to result in low-loss, high-efficiency, Energy Efficient Distribution Transformers (EE DTs). The no load losses can be reduced by 75% and load losses by 40% by using Copper windings in place of Aluminium windings.
ICA India engages in standardisation activity, carries out advocacy and capacity building amongst all stakeholders to adoption and effective implementation of new BIS Standards and BEE Energy Efficiency Labels (Star Rating).
Transformer Market Scenario
Indian Transformers market size is approx. 282,000 MVA in 2016-17. The market is expected to year on year growth around 5% mainly due to thrust in the power sector for providing universal access to electricity & reliable quality power for all in India.
Standards and Regulatory Scenario:
To spread awareness and facilitate the implementation of this order, ICA India in association with Bureau of Indian Standards (BIS) further supported by Central Electricity Authority (CEA), , MoP, GOI and Indian Transformer Manufacturer’s Association (ITMA) conducts regulatory capacity building activity to enhance understanding of various stakeholders for improvement in power distribution.
The focal point of these seminars was Standardization, Certification and Quality Control of Distribution Transformers. The seminars served as a platform for all power distribution stakeholders to come together for addressing concerns pertaining to regulatory compliance.
- Bring all the power distribution stakeholders on one platform to discuss and resolve issues pertaining to certification of Distribution Transformers as per IS:1180 (Part -1): 2014.
- Educate all stakeholders about the latest quality control order, relevant standards and mandatory BIS certification/registration requirements.
- Host interactive panel discussions to allow stakeholders to seek certifications from BIS officials and Accredited Test House representatives about certification process & testing.
