Current transformers
Accurate current measurement for energy metering and analysis Traditional current transformers, low-power current transformers and Rogowski coilsCurrent transformers make measurement currents greater than 5 A suitable for kilowatt-hour meters and analysers. Depending on the application, you can choose between traditional current transformers, low-power current transformers and Rogowski coils.
Traditional current transformers are also available in split-core versions, making them easy to retrofit in existing installations without disconnecting the primary conductor. Low-power current transformers provide a safe 333 mV output, are compact and eliminate the need for short-circuit terminals.
Rogowski coils are flexible and suitable for measuring very high currents and for installations with limited mounting space. For energy revenue metering, accurate 5 A current transformers are also available in accuracy classes such as 0.2S and 0.5S.
