Vettiner has over 50 years of expertise in magnetic lamination measurements, pioneering standards like NFC 28-911 and IEC 404-2/-3. Our standardised Epstein frame ensures precise testing of magnetic properties, such as losses and induction, in compliance with international standards. Designed for evolving needs, it supports testing across variable frequencies (up to kHz) and signal types, meeting modern demands for high inductions and advanced programmable power supplies. This makes our solutions ideal for R&D and performance assessments in transformers and electrical appliances.
