The Megger Smart Thump ST25-30 simplifies fault location on low and medium voltage cables up to 35 kV. Its E-Tray interface automatically runs a hipot test to identify fault type, measures cable length with TDR, then applies ARM Multishot for accurate pre-location before switching to surge pinpointing. The F-Ohm feature verifies safe earth connections before high voltage is applied, while the bright 7″ display remains readable outdoors.

Available in portable cart or vehicle-mount versions, the unit operates from internal battery, AC mains or 12 V DC and withstands wet conditions with its IP53 enclosure. Whether restoring power quickly or troubleshooting complex networks, the ST25-30 reduces cable stress and delivers reliable results with minimal operator input.
