Verification - PTB - Manuals

Instrument Transformers for revenue metering in Germany need a “declaration of conformity” according to the national verification act. One precondition for this declaration is a “type-examination-certificate”.

For new type-examination-certificate (2015 and later), a manual is allocated to the transformer type.

These manuals can be downloaded here. Since this is a specific German aspect (national verification act), these documents are available in German language only.
