Acceptance Testing and Maintenance of Power Transformer

An energy transformer is a rather critical piece of equipment and this makes its installation a monstrous task that needs to be well backed by a good testing and inspection program. Power transformer testing and inspection should ideally start with the... Read >

SPSU Photovoltaic (PV) Solar Converter Step-up Transformer

Difficulty in procuring non renewable fossil fuel, fluctuating global prices and growing environmental consciousness is pushing a growing number of industries in the United States to explore the profitability of alternate energy like wind and solar. T... Read >

NFPA Compliance and Electrical Transformers

Even though energy transformers typically deal with hazardous levels of electricity, they are often located in or near fairly public places. Their safety is thus a matter of much concern. For this reason, requirements for electrical transformers and emplo... Read >

Dry Type and Liquid-Filled Transformers: A Quick Comparison

Transformers under load generate heat due to winding (copper) and core losses occurring during operation. There is an 'acceptable' temperature rise for transformers used in power applications, and this can even limit their size. This acceptable temperatur... Read >

Grounding Transformers

Grounding is clearly one of the most important aspects of electrical design, but it steadfastly continues to be misinterpreted and misunderstood. Millions of dollars in liability and loss can be attributed to ground-fault arcing; thus, grounding-related i... Read >

Power Transformers Testing

Testing of transformer is done to determine their electrical, thermal and mechanical suitability for the system where they will be applied or used. Most of the tests performed on power transformers are defined in national standards created by IEEE, NEMA a... Read >
