Amorphous sheet core transformers under experimentation on the ERDF network

ERDF has already initiated a distribution network loss reduction process by modifying its specifications for conventional magnetic sheet transformers. ERDF has posted tenders for lowest responsible bidder that incorporate the evaluation of technical losses to encourage suppliers to work in this direction. Thus since the beginning of 2009, ERDF has been purchasing “reduced loss” transformers that enable it to cut no-load losses by 35–55%. ERDF is interested in amorphous sheet technology to halve its MV/LV transformer no-load losses to take matters forward in its determination to be an exemplary distributor in environmental terms. EDRF is committed to running experiments with this new equipment on the grid to support development of this new technical stage.
