The company was founded in 1927 by Emil Pfiffner in Hirschthal. PFIFFNER Instrument Transformers Ltd is the only instrument transformer manufacturer in Switzerland today. Large companies have stopped producing instrument transformers or relocated abroad. We were the smallest Swiss instrument transformer company in the 1990s, and we began to direct our activities consistently towards international markets. In 2004 PFIFFNER Transformatör Ltd was set up in Ankara. Other stages of expansion are the foundation of PFIFFNER do Brasil Ltd in 2006 and in 2010 the foundation of PFIFFNER Deutschland Ltd. In 2011 PFIFFNER R  & D has been founded as an independent company division. The PFIFFNER product range includes all current and voltage transformers, from low voltage up to the 550 kV high voltage level, from a few amps up to 50,000 amps in the giant power stations. We use the most up-to-date cast resins, oil-paper and SF6 -gas as dielectric medium. Besides inductive instrument transformers we also offer capacitive voltage transformers. PFIFFNER has become a fullservice provider of instrument transformers.
