I. Overview
SXJS-IV is an advanced instrument for measuring dielectric loss (tgδ) and capacitance (Cx), used under power frequency high voltage，to measure the dielectric loss (tgδ) and capacitance (Cx) of various insulating materials, insulating bushings, power cables, capacitors, transformers, and other high-voltage equipment. It replaces the QSI high-voltage bridge, featuring simple operation, Chinese display, printing, easy use, no conversion needed, built-in high voltage, strong anti-interference capability, and short test time. It is the third-generation intelligent dielectric loss tester from our factory.
