I. Overview of XJJBC Intelligent Variable Frequency Dielectric Loss Tester and Automatic Dielectric Loss Tester
The intelligent dielectric loss tester is an instrument for measuring dielectric loss (tgδ) and capacitance (Cx). It is used to measure the dielectric loss (tgδ) and capacitance (Cx) of various insulating materials, insulating bushings, power cables, capacitors, transformers, and other high-voltage equipment under power frequency high voltage. It replaces the QSI high-voltage bridge, featuring simple operation, Chinese display, printing, convenient use, no conversion needed, built-in high voltage, strong anti-interference capability, and short test time. In addition, this instrument, aiming at the difficulty of testing capacitive voltage transformers (CVT), adds external connection test methods, external standard capacitors, and voltage regulators, making the test very simple and reliable. It is the third-generation intelligent dielectric loss tester from our factory.
