Instrument Transformers

PFIFFNER offers a wide range of high voltage test possibilities in its several independent test fields.

In general, before leaving the factory, every instrument transformer is subjected to routine tests. In the medium and high voltage area, our products go through several test procedures, such as partial discharge and client or product specific tests. In this case, our internal test procedures are more stringent in part than those required by standards. Detailed measurements are made on every instrument transformer. The results are documented and their conformity to standards is reviewed.
