Vitrek 954i Ground Bond Hipot Tester

Overview

The Vitrek 954i is a DSP-based electrical safety compliance analyzer designed for high-performance dielectric and leakage current testing. It offers combined hipot, insulation resistance (IR), ground bond (GB), and leakage resistance (LR) capabilities in a single, compact instrument. The 954i delivers 11 kVDC/6 kVAC output with pico-amp resolution measurement and is ideal for demanding electrical safety test applications across multiple industries.
