In view of the ever-increasing use of transformers in industrial and commercial operations, the necessity to maintain a high safety level has become more and more important. The need for clear technical requirements is therefore crucial.
CLC/SR 96 'Transformers, reactors, power supply units, and combinations thereof' develops, in close cooperation with its IEC counterpart, European Standards in the field of safety, EMC, EMF, energy efficiency and environmental aspects of transformers, reactors, power supply units, and combinations thereof.
CLC/TC 14 'Power Transformers' is responsible for standardization in the field of power transformers, tap-changers, and reactors for use in power generation, transmission and distribution. Generally, these transformers have power ratings above 1 kVA single-phase and 5kVA polyphase with a higher voltage winding of 1000V or more, however the scope includes lower voltage transformers and regulators used in power delivery applications. CLC/TC 14 is notably active in the field of Ecodesign and provide ENs in support of Regulation 2019/1783.
CLC/TC 38 ‘Instrument transformers’ develops European Standards (using whenever possible IEC Standards) in the field of AC and/or DC current and/or voltage instrument transformers, including their subparts like (but not limited to) sensing devices, signal treatment, data conversion and analogue or
digital interfacing”
