In addition to a comprehensive range of standard current transformers in accuracy classes 0.5 and 1, GMW has a wide range of current transformers for current ranges from 25 A to 3000 A in the accuracy classes 0.2s, 0.2, 0.5s, 0, 5th since 1 January 2015, conversion converters have been placed on the market in Germany following the conformity assessment procedure.

Transducers (Module B) approved by the „Physikalisch Technische Bundesanstalt (PTB) Braunschweig“ are identifiable with a generic and design number arranged in a stylized “S”.

The usual GMW type designation is additionally preceded by an “E”.

The conformity of the transducers is documented by a yellow conformity mark as well as a declaration of conformity enclosed with the goods.

The quality assurance system is recognized by PTB in accordance with module D of the conformity assessment procedure, so that the offsetting converters can be used directly for invoicing purposes.

For other European countries, these type-approved current transformers have permits for billing purposes.
