Product Introduction:
It features non-contact between the oil cup and heating element, uniform heating, fast speed, and convenient control. The AC test power supply uses AC-DC-AC conversion to effectively avoid the impact of mains voltage and frequency fluctuations on the accuracy of dielectric loss testing. Even when powered by a generator, the instrument can operate correctly. It adopts an LCD Chinese character display interface, with all operations prompted by Chinese menus. The instrument is equipped with a panel printer and can store 500 measurement data records, which will not be lost even when the power is turned off. When using the reverse connection method for measurement, signals are transmitted via optical fiber, isolating high voltage and ensuring safe operation. The instrument uses a microcomputer for information and data processing, automatically selects the measurement range, and has high measurement accuracy. It uses frequency conversion technology for good anti-interference against external electric fields, and sudden power failure during the voltage boosting process will not cause overvoltage. It is simple to operate and convenient to use.
It is a new generation of automated instruments for measuring dielectric loss tangent (tgδ) and capacitance value (Cx). It can measure the dielectric loss tangent (tgδ) and capacitance value (Cx) of various insulating materials, insulating bushings, power cables, capacitors, transformers, and other high-voltage equipment on-site under power frequency high voltage. The transformer oil dielectric loss tester is also suitable for measuring tgδ and capacitance of high-voltage electrical equipment in workshops, laboratories, and scientific research institutions; with an insulating oil cup, it can test the dielectric loss of insulating oil.
It is a very important tool commonly used by power supply bureaus, power plants, and other departments. There are also many manufacturers, and the market is somewhat chaotic, especially with some inferior products flooding the market.
