Guidelines on Energy Efficiency of Electrical Installations

A typical insulating gas gas sealed type 1500 kVA 3-phase 11kV/380V distribution transformers used in Hong Kong have a total weight of about 5,000kg. The transportation of these distribution transformers from ground floor level to their high level substations in a high -rise building might therefore pose a major problem. 4.2 Minimum Transformer EfficiencyGet price
