Partial Discharge Testing for Switchgear | Vertiv Services

Your medium-voltage switchgear is vulnerable to PD if it has voids, gaps, or other defects. PD can also occur on the surface of insulators. Left unchecked, these small electrical sparks erode insulation and lead to unplanned outages. PD testing for switchgear helps you prioritize maintenance resources and take action before this failure occurs.Get price
