CFL SG 3210 Surge Generator (High-Energy Series)

The CFL SG 3210 is a high-energy surge generator for fault location on medium- and high-voltage power cables up to 33 kV. With selectable output ranges of 0–8 / 16 / 32 kV and up to 1000 J per range, it supports all standard fault location methods when paired with CFL Prelocators and Pinpointing Systems.
Equipped with integrated safety interlocks, automatic discharge, and optional DC testing and burn modes, the SG 3210 is a versatile field-ready platform for accurate, safe, and repeatable cable fault diagnostics.
