Trilateral comparison of measurements on electrical sheet steels

Project Description

Due to the possibility of a discrepancy in measurements being undertaken as part of work on an IEC standard, it became appropriate to conduct at short notice, a comparison of the measurements of the AC magnetic properties of a set of samples of electrical sheet steel.

The measurements done were of the specific total power loss and the specific apparent power at 50 Hz in an Epstein frame. The measurements are made in accordance with IEC Standard 404 Part 2.
