What defines the new TIER2 ecodesign norm for transformers?
The new TIER2 ecodesign norm for transformers is a set of standards and regulations that are intended to improve the environmental performance of transformers. The norm was developed by the European Commission, and it establishes minimum requirements for the energy efficiency, sound power, and no-load losses of transformers. The main goal of the TIER2 ecodesign norm for transformers is to ...

Transformer oil purification
Why degas transformer oil? Maybe the first question should be, “why is it important to have purified oil in a transformer?” Dissolved gasses in transformer oil can cause arcing, corona discharges, and overheating--reducing the electrical efficiency and lifetime of the transformer. Likewise, water contamination at levels as low as 30 ppm (parts per million) can adversely affect the ...

What are the products of power cable
The main features of power cable products are: extruding (winding) an insulating layer on the outside of the conductor, such as overhead insulated cables, or twisting several cores (corresponding to the phase wire, neutral wire and ground wire of the power system), such as overhead insulation with more than two cores cable, or add a jacket layer, such as plastic/rubber sheathed wire and cable. ...

Magnetising inrush current in transformers: an overview
In India, the failure rate of distribution transformers has been reported very high especially in the rural and remote areas. In these areas, frequent inrush current is produced in distribution transformers during their energisation. The generation of inrush current during each energisation may be dangerous for health of the distribution transformers. This has motivated the authors for extensive ...
