SG12.800 Compact High Voltage Surge Generator

The SG12.800 Compact is a lightweight, portable high-voltage surge generator designed for cable fault location and insulation testing in low- and medium-voltage networks. Delivering up to 12 kV output with 800 J surge energy, it supports DC withstand testing, TDR methods, ICM impulse current, and MIM/ARC multiple impulse methods (with TDR.950A). It can also be paired with GM Series acoustic pinpointing receivers for precise fault location. Housed in a rugged 25 kg moulded case with wheels, it is optimized for easy transport, safety, and reliable field performance.
