Protective relay maintenance and re-commissioning

The duration of the routine test cycles defined by a utility depend heavily on the type of relays that have been installed. For instance, numerical relays are not tested as frequently as their electro-mechanical ancestors. However, most utilities still perform tests due to the possibility of firmware upgrades or other changes which might influence the reliability of their protection system.

For maintenance and re-commissioning, our CMC test sets combined with the powerful Test Universe software allow you to re-use test plans for automated testing, which were originally used to commission relays. We also offer a wide range of accessories including equipment for GPS synchronized testing. ADMO, our easy-to-use data and maintenance management software helps you to keep track of all your testing tasks.
