What is a distribution transformer?
Distribution Transformer: An Essential Component of Power Distribution Systems As you go about your daily life, you probably take for granted that electricity is readily available to power your home and business. However, there is a complex system in place that allows for the efficient distribution of electrical power, and one key component of this system is the distribution transformer. What ...

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 ...

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. ...

How to choose the cross-sectional area of the power cable
The choice of the cross-sectional area of the power cable is related to the investment, the loss and voltage quality of the line, and the service life of the cable. If the cross-sectional area of the power cable is too small, the voltage quality will drop, the line loss will be too large, and the initial investment will be too high. Therefore, the appropriate cross-sectional area should be ...

How to Improve Power Reliability for Semiconductor Fabs
Semiconductor fabs use up to 100 megawatt-hours of power each and every hour Semiconductor manufacturing facilities require a massive amount of energy to support their facilities and manufacturing processes. Large fabs can use as much as 100 megawatt-hours of power each hour – more than many oil refineries and automotive plants. Energy use will continue to increase with higher production ...

MGM makes transformers for solar applications
Scientists have high confidence that global temperatures will continue to rise for decades to come, largely due to greenhouse gases produced by human activities. The Intergovernmental Panel on Climate Change (IPCC), which includes more than 1,300 scientists from the United States and other countries, forecasts a temperature rise of 2.5 to 10 degrees Fahrenheit over the next century. Increasing ...

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 ...

Renewable energy solutions: Necessity not choice
An elite gathering of Asia Utility firms speak out on the need to go Green. The Energy industry has become a key talking point globally. Renewable energy solutions are no longer optional but a necessity which must be embraced by all governments. Driven by China’s determination to reduce their dependence on coal energy and to look ahead to a more sustainable future, the recent NGU APAC summit ...

Succeeding in a carbon-constrained world
The author details the inevitability of a stronger U.S. climate change policy, the increasing business leadership on climate issues, the factors that influence corporate climate strategies, and the effective business strategies that address climate change. Although it may yet be several years before the United States enacts greenhouse gas (GHG) regulation, a profound transformation is beginning ...

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 ...
