EMC testing: Part 6 - Low-frequency magnetic fields; mains dips, dropouts, interruptions, sags  image #1

This is the sixth in a series of seven bi-monthly articles on ‘do-it-yourself’ electromagnetic compatibility (EMC) testing techniques for apparatus covered by the EMC Directive (EMCD).

This series covers the whole range of test methods – from simple tests for development and fault-finding purposes, through lowest-cost EMC checks; ‘precompliance’ testing with various degrees of accuracy; on-site testing for large systems and installations; to fullspecification compliance testing capable of meeting the requirements of national test accreditation bodies. Previous articles are available on-line at www.compliance-club.com, using the site’s Archive Search facility.
