Subject matter and scope
Article 1
1. This Regulation establishes ecodesign requirements for placing on the market or putting into service power transformers with a minimum power rating of 1 kVA used in 50 Hz electricity transmission and distribution networks or for industrial applications. The Regulation is only applicable to transformers purchased after the entry into force of the Regulation. 2. This Regulation shall not apply to transformers specifically designed and used for the following applications: — instrument transformers, specifically designed to supply measuring instruments, meters, relays and other similar apparatus, — transformers with low-voltage windings specifically designed for use with rectifiers to provide a DC supply, — transformers specifically designed to be directly connected to a furnace, — transformers specifically designed for offshore applications and floating offshore applications, — transformers specially designed for emergency installations, — transformers and auto-transformers specifically designed for railway feeding systems, — earthing or grounding transformers, this is, three-phase transformers intended to provide a neutral point for system grounding purposes, — traction transformers mounted on rolling stock, this is, transformers connected to an AC or DC contact line, directly or through a converter, used in fixed installations of railway applications, — starting transformers, specifically designed for starting three-phase induction motors so as to eliminate supply voltage dips, — testing transformers, specifically designed to be used in a circuit to produce a specific voltage or current for the purpose of testing electrical equipment, — welding transformers, specifically designed for use in arc welding equipment or resistance welding equipment, — transformers specifically designed for explosion-proof and underground mining applications ( 2 ) , — transformers specifically designed for deep water (submerged) applications, — medium Voltage (MV) to Medium Voltage (MV) interface transformers up to 5 MVA, — large power transformers where it is demonstrated that for a particular application, technically feasible alternatives are not available to meet the minimum efficiency requirements set out by this Regulation, — large power transformers which are like for like replacements in the same physical location/installation for existing large power transformers, where this replacement cannot be achieved without entailing disproportionate costs associated to their transportation and/or installation, except as regards the product information requirements and technical documentation set out in Annex I, points 3 and 4.
