Preventing Failure
Selection of the Circuit Breaker has to be done carefully, so that it does not allow the transformer to exceed the permissible winding temperature. The built-in Bi-metallic strips mounted in the Circuit Breaker, located below the top oil, achieve the temperature sensing function. The circuit breaker thus provides Thermal matching with the transformer & protects it against over loads... - C.V.Govinda Raju

Dielectric Technology in Transformer
Utilities and transformer manufacturers focus on the design and manufacture of environmentally-friendly transformers that are nonhazardous while offering improved life cycle costs with minimal maintenance. These transformers offer reduced carbon footprint, reduced levels of pollution (water, soil, noise), enhanced lifecycle costs, enhanced product lifetime, and enhanced fire safety…
High Efficiency Distribution Transformers
Due to use of better grade materials and optimum design, sudden failures are reduced along with lower cost of maintenance, leading to increased life expectancy. These benefits add up and balance against the inevitable increase in purchase cost – as additional copper in the windings and better materials in the core will be used in the manufacture of high efficiency transformers... - S V Varadarajan

Power Transformer Market worth US$ 29.91 Bn by 2020
The growth is due to the increase in HVDC transmission projects mainly in the Asia-Pacific region. HVDC, EHV, and UHV projects being undertaken for reducing transmission losses during transmission over large distances is the major growth driver of the large power transformer market.
Easing Multi-function Testing
There is only one instrument to unpack, power up and configure; the same cable set is used for a whole range of measurements, so the connections only need to be made once; and, when carrying out a range of tests, users of multifunction instruments move quickly and easily from app to app, rather than having to go from instrument to instrument... - Peter Fagerström
