Test Facilities & Laboratories
PFIFFNER laboratories covers all required routine tests on instrument transformers according the international standards and performs them in the own laboratories. The laboratories tests instrument transformers from low voltage to high voltage insulated with different mediums such as oil, SF6 or resin.
On top PFIFFNER has the knowledge and ability to perform all type and special test on instrument transformers and general high voltage tests according the relevant international standard up to Um <= 550 kV.
