The DCJS-H variable frequency dielectric loss tester, also known as the variable frequency dielectric loss tester or anti-interference variable frequency dielectric loss tester and fully automatic variable frequency dielectric loss tester, is suitable for dielectric loss detection tests in power plants, substations, transformer manufacturers, and power maintenance departments. The variable frequency dielectric loss tester is suitable for dielectric loss tests on electrical equipment with moisture-induced deterioration, local defects, equipment installation, handover, and preventive maintenance.



The DCJS-H fully automatic anti-interference dielectric loss tester is a high-precision dielectric loss tester developed by the R&D department of Wuhan Dingsheng Electric Power, referencing the latest industry standards and power test regulations. The DCJS-H fully automatic anti-interference dielectric loss tester is suitable for power plants, substations, transformer manufacturers, and power maintenance departments. It is a high-precision tester that automatically measures the dielectric loss tangent and capacitance of various high-voltage power equipment. Due to the adoption of frequency conversion technology, it filters out interference generated by the power frequency on-site, ensuring accurate measurement under strong electric field interference. The tester uses a Chinese menu operation interface, and the microcomputer automatically completes the entire measurement process. 

      The DCJS-H variable frequency dielectric loss tester's dielectric loss insulation test can effectively detect overall moisture-induced deterioration, local defects, etc., in electrical equipment insulation. It is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive tests. It adopts frequency conversion power supply technology, using single-chip microcomputer and electronic technology for automatic frequency conversion, analog/digital conversion, and data processing, achieving strong anti-interference capability, fast test speed, high precision, and simple operation. The frequency conversion power supply uses a high-power switching power supply, outputting pure sine waves at 45Hz and 55Hz, with automatic voltage boosting, providing up to 10kV voltage, and automatically filtering out 50Hz interference. The DCJS-H variable frequency dielectric loss tester is suitable for on-site testing in substations and other environments with significant electromagnetic interference.
