KEJSY-A Anti-Interference Dielectric Loss Tester

I. Instrument Overview
      The KEJSY-A Anti-Interference Dielectric Loss Tester is an advanced instrument for measuring dielectric loss (tanδ) and capacitance (Cx). It is used under ultra-frequency, variable frequency, and power frequency high voltage to measure the dielectric loss (tanδ) and capacitance (Cx) of various high-voltage equipment such as insulating materials, insulating bushings, power cables, capacitors, transformers, and instrument transformers.
       This tester replaces the QSI high-voltage bridge and offers advantages such as simple operation, Chinese display, printing, ease of use, no need for conversion, built-in high voltage, and the use of frequency conversion technology, resulting in strong anti-interference capability and short testing time. Additionally, this dielectric loss tester addresses the challenges of testing capacitive voltage transformers (CVT) by adding an external method for testing with external standard capacitors and voltage regulators, making testing very simple and reliable. It is the fourth-generation intelligent anti-interference dielectric loss tester developed by our company.
