PLD108A type oil volume resistivity Dielectric Loss Tester
Characteristic：
1. highly automated, heating, measuring dielectric loss and measuring resistivity can be completed at one time.
2. the oil cup adopts the three electrode structure conforming to the national standard GB/T5654-2007, and the interelectrode spacing 2mm can eliminate the influence of stray capacitance and leakage on dielectric loss test results.
3, the instrument uses intermediate frequency induction heating, PID temperature control algorithm. The heating method has the advantages of non contact with oil cup and heating body, uniform heating, fast speed, convenient control and so on, so that the temperature is strictly controlled within the range of the preset temperature error.
4, adopt advanced DSP and FFT technology to ensure data stability, accuracy and reliability.
5, the internal standard capacitor is SF6 inflated three point polar capacitance. The dielectric loss and capacitance of the capacitor are not affected by the ambient temperature and humidity, so that the precision of the instrument is still guaranteed for a long time.
6, large screen color touch screen, Chinese operation menu, convenient dialogue, simple operation, clear at a glance.
7, with the opening and breaking of high pressure, oil cup high and low voltage electrode short circuit and other warm hints to eliminate security risks, to ensure the safety of the operator and the normal operation of the equipment.
8, with a real-time clock, the test date and time can be saved, displayed and printed with the test results. The device can display real-time monitoring of the environment.
9, automatic storage of measurement data, can store 100 sets of measurement data.
10. empty electrode cup calibration function. The capacitance and dielectric loss factor of the empty electrode cup are measured to judge the cleaning and assembly status of the empty electrode cup. The calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
