The AC test power supply adopts the AC-DC-AC conversion method, which effectively avoids the influence of the mains voltage and frequency fluctuations on the accuracy of the dielectric loss test. Even if the generator generates electricity, the instrument can run correctly.
Perfect protection function. When there is overvoltage, overcurrent, or high voltage short circuit, the instrument can quickly cut off the high voltage and issue a warning message. When the temperature sensor fails or is not connected, a warning message is issued. There is a temperature limit relay in the intermediate frequency induction heating furnace. When the temperature exceeds 120 degrees, the relay is released and the heating stops.
Empty electrode cup calibration function. Measure the capacitance and dielectric loss factor of the empty electrode cup to judge the cleaning and assembly condition of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculations of relative permittivity and DC resistivity.
DLT-I High Precision Insulating Oil Dielectric Loss Tester is based on the RAM9 platform, with high test accuracy and fast speed.
