Automated testing for electromechanical overcurrent relays

Despite the advance of numerical technology, electromechanical relays will still be around for a long time. So testing of these relays will remain an issue in the future. There are, however, some special problems when testing electromechanical relays with electronic test sets, commonly summarized under the term power demand. These problems can be overcome with state of the art testing equipment. Furthermore, modern testing software can offer increased efficiency in the testing and setting of electromechanical relays
