MS-101YTransformer Insulation Oil Tan Delta Tester 

Transformer Insulation Oil Dielectric Loss Tester: The transformer insulation oil dielectric loss tester is used to accurately measure the dielectric loss factor (tanδ) of insulating oil.

This parameter sensitively reflects the deterioration of insulation performance caused by polar impurities, aging products, and trace amounts of water in the insulating oil. Its core purpose is to evaluate the energy loss of the oil under an alternating electric field, and it is a key indicator for judging the purity and aging degree of the oil, which is more sensitive than the breakdown voltage test.

1. Highly automated: Heating, dielectric loss measurement, and resistivity measurement can be completed in one go;
2. The oil cup adopts a three-electrode structure conforming to the national standard GB T5654-2007, with a 2mm electrode gap, which eliminates the influence of stray capacitance and leakage on the dielectric loss test results;
3. The instrument uses medium-frequency induction heating and PID temperature control algorithm. This heating method has the advantages of non-contact between the oil cup and the heating element, uniform heating, fast speed, and convenient control, ensuring that the temperature is strictly controlled within the preset temperature error range.
4. Advanced DSP and FFT technology are used to ensure stable, accurate, and reliable data.
5. The internal standard capacitor is an SF6 charged gas three-electrode capacitor. The dielectric loss and capacitance of this capacitor are not affected by ambient temperature, humidity, etc., ensuring the accuracy of the instrument even after long-term use.
6. Color touch screen, convenient operation menu, simple and clear operation at a glance.
7. It has safety features such as high-voltage cut-off when the lid is opened and short-circuiting of the high and low voltage electrodes of the oil cup, eliminating safety hazards and ensuring the personal safety of operators and the normal operation of the equipment.
8. Built-in real-time clock: Test date and time can be saved, displayed, and printed with the test results; the device can display the ambient temperature and monitor the test environment in real time.
9. Automatic storage of measurement data: 100 sets of measurement data can be stored.
10. Empty electrode cup calibration function. Measures the capacitance and dielectric loss factor of the empty electrode cup to determine the cleaning and assembly status of the empty electrode cup. Calibration data is automatically saved to facilitate accurate calculation of relative permittivity and DC resistivity.
