♦ Fully automatic, temperature rising and dissipation measuring could be completed by one time.
♦ Oil vessel is three-electrode type, pole's gap is 2mm, to eliminate the stray capacitance and leakage influence on the measuring results.
♦ Heating by medium frequency induction method, PID temperature controlling algorithm. The oil vessel is not contacted with heating unit, heating uniformly fast and controlled easily, so that to control the temperature within the pre setting error range.
♦ The reference capacitor is SF6 gas three three-electrode type, which dielectric loss and capacitance will not be effected by environment temperature, humidity and etc, to ensure the high precision even the tester was used for a long time.
♦ Auto stored test data, total storage is 100 groups.

How does the dielectric loss factor affect the insulation performance of transformer oil?
1. Insulation resistance: The dielectric loss factor is directly related to the insulation resistance of the transformer oil. A lower dielectric loss factor indicates higher insulation resistance, which means the oil can better resist the flow of electric current, thus improving its insulating capability.
2. Dielectric strength: The dielectric loss factor is an indicator of the dielectric strength of the transformer oil. A lower dielectric loss factor suggests higher dielectric strength, which means the oil can withstand higher electric fields before breaking down and allowing current to flow.
3. Heat generation: The dielectric loss factor is related to the amount of heat generated within the transformer oil when exposed to an alternating electric field. A higher dielectric loss factor leads to greater heat generation, which can accelerate the aging and degradation of the oil, reducing its insulating properties over time.
4. Moisture and contaminant detection: The dielectric loss factor is sensitive to the presence of moisture and contaminants in the transformer oil. An increase in the dielectric loss factor can indicate the presence of moisture, polar contaminants, or aging by-products, which can compromise the insulating performance of the oil.
5. Aging and degradation: As transformer oil ages and degrades over time, its dielectric loss factor tends to increase. Monitoring the dielectric loss factor can provide insights into the condition of the oil and help determine when it needs to be reconditioned or replaced to maintain optimal insulation performance.
