SG32.4000ST High Voltage Surge Generator System

The SG32.4000ST is a high-energy surge generator designed for advanced high-voltage cable fault testing. With surge energy up to 4096 J and DC withstand voltage testing up to 32 kV, it supports a wide range of diagnostic methods including TDR (Time Domain Reflectometry), ARC Reflection Method, Impulse Current Method, and acoustic pinpointing (with GM Series receivers). Its rugged IP54-rated design, safety functions, and modular configuration make it suitable for demanding field and substation environments.
