Transforming energy by trying to “waste” as little of it as possible, this is the goal we must aim for immediately. Whether for industrial applications (paper mills, chemical industries, cement factories, mines), for commercial applications (offices, universities, hospitals, hotels), for railway or naval applications, the imperative is ENERGY EFFICIENCY.

From this point of view, the favorable regulations for the use of transformers, designed to minimize losses and improve energy efficiency, are of importance.
New CTA, which for years has been sensitive to the issue of reducing load and no-load losses, designs transformers by carefully selecting and using materials of the highest quality, which guarantee high performance, with very low losses and lower greenhouse gas emissions.

Reducing electricity consumption, using high efficiency transformers and careful load management, produces a series of essential benefits in the current energy scenario:

1. reduction of costs incurred in energy
2. reduction of the pollution of the planet.

Therefore high quality transformers allow to achieve substantial savings over time.
For example, in the specific case of no-load losses, the reduction can be achieved by using, in the core of the transformer, types of lamination with high magnetic permeability. To fully understand the advantages of using quality components and highly specialized production techniques, just consider that the loss in ordinary laminations can reach values in the order of 20-30% higher than the loss of laminations with high magnetic permeability.
It is also important to point out that, from the point of view of size and weight, the use of low-loss transformers does not imply any need to reconfigure the transformer substation.

Ultimately, the losses materialize above all in an expense, as the dispersed energy is still supplied by the network and therefore reported.
A clear picture of the real energy efficiency resulting from the use of higher quality transformers can be found considering the total annual losses suffered by the transformer fleet in the EU: they reach a maximum amount of 93.4 TWh! The potential for improvement in terms of costs, generated by a specialized and consolidated design of transformers, is estimated for 2025 to be around 16.2 TWh per year, equal to 3.7 Mt of CO2 emissions (5 times less than today!)
Normally the cost of replacing a more efficient transformer is reabsorbed within 2-3 years of operation, with substantial savings on energy costs … and on our ecosystem.
