From concept to demonstration, this video highlights the evolution and practical outcomes of the SXGTU GIS Partial Discharge and Withstand Test System. You'll see how this high-voltage AC withstand and electrical insulation testing equipment operates in real-world scenarios, including its sealed shielded design that controls partial discharge within 1–3 pC. Watch as we demonstrate the compact, lightweight structure, internal high-voltage isolation switch, and flexible testing arrangements for GIS applications.
