Ground fault protection systems come from the factory with several potential error points, and more can be added during installation. As such, it’s important to always test these systems during commissioning to avoid nuisance trips to correct difficult-to-troubleshoot problems.
In this article from NETA World, Mose Ramieh, vice president of business development at CBS Field Services, provides an in-depth explanation of both the importance of ground fault protection testing and its proper procedure. He also highlights some of the potential complications that can arise during this process, as well as steps to take to troubleshoot a suspected ground fault trip.
Additionally, Ramieh shares some real-life case studies related to busbar-mounted current transformers he’s encountered in the field.
