Description

BS PD IEC/TS 60076-20:2017 is applicable to transformers in the scope of IEC 60076-1.

The energy performance levels given in Clause 6 are not applicable to the followingtransformers:

  • transformers for high current rectifiers as described in the IEC 61378 (all parts) and in theIEC 60146 (all parts);
  • transformers for furnace applications;
  • transformers for offshore applications;

NOTE 1 Transformer to be installed on fixed or floating offshore platforms, offshore wind turbines or on board ofships and all kind of vessels).

  • transformers for emergency or temporary mobile installations;

NOTE 2 Transformers designed only to provide cover for a specific time limited situation when the normal powersupply is interrupted either due to an unplanned occurrence such as failure or a station refurbishment, but not topermanently upgrade an existing substation.

  • traction transformers;
  • earthing transformers as described in 3.1.10 of IEC 60076-6:2007.
  • phase shifting transformers;
  • instrument transformers (IEC 61869-1);
  • transformers and auto-transformers specifically designed for railway feeding systems, asdefined in EN 50329;
  • traction catenary supply transformer for 16,67 Hz;
  • transformer for high current rectifiers (IEC 61869-1);

NOTE 3 These are transformers specifically designed and intended to supply power electronic or rectifier loadsspecified according to IEC 61378-1.

NOTE 4 This exclusion does not apply to transformers intended to provide AC power from DC sources such astransformers for wind turbine and photo voltaic applications as well as transformers designed for DC transmissionand distribution applications.

  • transformers for railway feeding systems (EN 50329);
  • subsea transformers;
  • starting-, testing- and welding transformers;
  • starting transformers, specifically designed for starting three-phase induction motors so asto eliminate supply voltage dips;

NOTE 5 Examples are transformers that are de-energised during normal operation, used for the purpose ofstarting a rotating machine).

  • transformers specifically designed for explosion-proof and underground miningapplications;
  • transformers which cannot fulfil the energy performance requirements due to unavoidablesize and weight limitations.

NOTE 6 Due to the unavoidable weight and size limitation for a rolling stock application, this definition includes alltraction transformers for rolling stock, irrespective of the frequency (e.g. 16,7 Hz, 25 Hz, 50 Hz, 60 Hz).
