  • In Japan about 16 million units of distribution transformers are in service. These transformers are expending a huge amount of energy in the form of no load loss and load loss. Among these losses, no load loss is major. No load loss can be saved dramatically by changing these transformers to amorphous transformers (i.e., amorphous metal-based transformers). This paper estimates the scope of the possible energy saving and reduction of CO2 emissions by the adoption of amorphous transformers in Japan and in China.

  • A widespread use of high efficiency transformers could save the world 100 TWh/year. Under normal conditions, purchasing high efficiency transformers is both economically and environmentally sound. In the liberalized European energy market however, the regulatory and financial framework obstructs utility companies from making long term investments like purchasing high efficient transformers. National regulators put pressure on utility companies to do cost cutting and do not compensate with sufficient incentives for energy efficiency. According to this paper, there is a heterogeneous treatment between generation on renewable energy and transformer efficiency. Yet the greenest kWh is still the one that is saved, even when it is compared to a kWh derived from a renewable source.

  • The lower bound of generation is NOT zero, as implied by the graph, but is actually negative when the windmill is not generating. The core is excited from the HV side, just like in a distribution system. When there is no generation, the transformer actually pulls power from the grid. For renewables, you should be using transformers with amorphous metal cores which cut no load losses by 70 percent.

    "This paper describes the performance of the network of a typical future residential concept area, as has been studied in the Intelligent E-Transportation Management project. Several scenarios have been elaborated by load flow simulations. The study investigated what level of introduction of electric vehicles, heat pumps, photovoltaic systems and micro- combined heat and power plants is feasible in this network. Possible overload situations are examined and the opportunities of demand side management for the power grid are investigated. In general load-flow simulations show that transformer overloads will occur when electric heat pumps and electric vehicles are introduced together in this specific grid. In that case extension of the grid or of the transformer capacity is necessary. Alternatively, demand side management can be applied successfully to mitigate the overload."
