Power transformers are the most expensive and critical pieces of equipment in a power distribution system. Ensuring they are running to optimum capacity and in good condition is thus crucial. Fault detection techniques serve as a warning to developing abnormalities in a transformer; and these techniques have many parameters of measurement and visual inspection.
Present-day transformers are ...

The USA is the largest power consumer in the world. Unfortunately a large portion of the aging USA power distribution grid was installed prior to 1990. That being said, a large installed base of transformers are nearing the end of their useful life expectancy and change-out or replacement should be part of every owner’s strategy for system reliability.
Modern liquid ...

As fuel costs rise and power outages become more prevalent around the country, the power generation and distribution system in the US has come into sharp focus. So too has the need to conserve energy and the need to invest in energy-efficient products of all types. Of particular interest are products like power transformers that remain energized and consume energy 24 hours a day.
The ...

In the rush to cash-in on wind energy, developers are often trading low first costs for higher total costs of ownership to be shouldered later by the wind farm owners and operators
Converting wind energy to electrical power is the fastest growing segment of the US energy sector. Today, wind energy represents less than 5% of the US electrical generation and is targeted to reach 20% in the ...

In order to maximize the lifetime and efficacy of a transformer, it is important to be aware of possible faults that may occur and to know how to catch them early. Regular monitoring and maintenance can make it possible to detect new flaws before much damage has been done. The four main types of transformer faults are: Arcing, or high current break down Low energy sparking, or partial ...
