However, attention is drawn to the fact that during the development of this European Standard the UK committee vo

10、ted against its approval as a European standard. The UK committee submitted a negative vote for the following reasons: a) This standard is not applicable to transformers for tram systems, which have the same, or similar, operating characteristics to railways. The UK committee is of the opinion that

11、the relevant exclusion in clause 1 should read transformers and auto-transformers specifically designed for railway and other traction feeding systems. b) The UK committee advises that the de-energised tapping range for single-phase liquid immersed transformers with Sr 100 kVA should be 7,5 % as thi
