Wuhan Web Science the Austrian three high Electrical Equipment Co., Ltd. - Wajs-101D interference dielectric loss tester (light board) Overview: dielectric loss insulation test can be found the overall damp degradation of the electrical equipment, insulation deterioration, as well as local defects in the electrical manufacturing , are widely used in the installation of electrical equipment, and preventive testing. Interference dielectric loss tester with variable frequency power supply technology, the use of single-chip and electronic technology for automatic frequency conversion, analog / digital conversion and data operations, to achieve the anti-interference ability, test speed, high precision, easy to operate features. Inverter power supply with power switching power supply, the output 45Hz and 55Hz pure sine wave, automatic compression, which provides the highest voltage 10kV 50Hz interference; automatically filtered out, and apply to substations and other electromagnetic interference field test. Features: 1, the self-excitation method with the CVT test, a wiring, simultaneous measurement of the capacitance of C1, C2 and tg | ?. 2, with anti-wiring low voltage shielding, in CVT bus grounding, the C11 can be no stitches 10kV anti-wiring dielectric loss measurement. 3, with the function of the applied voltage and applied CN measurements. Instruments to measure high accuracy to meet the measurement requirements of the oil dielectric loss, so only with standard oil cup, and a dedicated test line can be realized oil dielectric loss measurement. 5, the use of inverter technology to eliminate on-site 50Hz frequency interference, even in the environment of strong electromagnetic interference can be measured reliable data. 6, ground fault protection function, when the instrument is not grounding wire or poorly grounded, the instrument does not enter the normal procedures, the high-voltage output. 7, overcurrent protection, short-circuit or breakdown of the test instrument from damage. 8, is equipped with a standard capacitor and high voltage power supply, easy on-site testing, reducing field wiring. The instrument uses a large-screen LCD display, the testing process through the Chinese menu is intuitive and easy to operate.
