Wondering how a single cable fault surge generator can handle three different voltage levels? In this video, we demonstrate the XHHV535-4TS trolley-mounted surge generator with selectable 8kV, 16kV, and 32kV outputs. Watch as we show how field technicians can switch between voltage levels for distribution, industrial, and sub-transmission cable testing without equipment changes. See the operational workflow, safety features, and real application scenarios that make this multi-voltage unit essential for utility and contracting teams.
