SG5.500SMT Compact High Voltage Cable Fault Location System

The SG5.500SMT is a compact surge generator system designed for cable fault location and insulation testing in low-voltage networks. With an output of 0–5 kV and 500 J surge energy, it supports DC withstand testing, TDR methods, ICM impulse current, and MIM/ARC multiple impulse methods (with TDR.950A). Integrated with TDR 750A (included) and compatible with GM Series acoustic pinpointing receivers, the SG5.500SMT is optimized for safe, precise, and portable field fault diagnostics.
