Application Scenarios
1. New Oil Acceptance:
Newly procured transformer oil: Verify purity and initial insulation properties meet specifications.
2. In-Service Oil Monitoring:
Transformer oil in operation: Conduct periodic testing to track aging trends.
3. Fault Diagnosis:
Abnormal transformer oil: Assist in analyzing fault causes (e.g., overheating, moisture ingress).
4. Oil Filtration/Regeneration Effect Verification: Treated transformer oil: Verify whether its insulation properties are restored after filtration or regeneration treatment.
Key Features & Advantages
Main features
(1) The oil cup complies with the three-electrode design specified in the national standard GB/T5654-2007, with a distance of 2 mm between the electrodes. This design eliminates the influence of parasitic capacitance and the Schottky effect on the results of dielectric loss tests.
(2) The device uses medium-frequency induction heating with PID temperature control algorithms. The oil cup heating mode uses a non-contact heating element, which ensures uniform heating, fast response and convenient adjustment, thereby maintaining the temperature within the specified tolerance range.
(3) The built-in standard capacitor uses a tripolar capacitor filled with SF6, whose dielectric loss and capacitance are independent of the ambient temperature and humidity. This ensures stable measurement accuracy over a long period of operation.
(4) The AC power supply uses an AC-to-DC conversion method, effectively reducing the impact of mains voltage and frequency fluctuations on the accuracy of dielectric loss measurements. The device operates reliably even when powered by a generator.
(5) Ideal protection function. In the event of overload, overcurrent, or high-voltage short circuit, the device can quickly disconnect the high pressure and send a warning message. In the event of a malfunction or lack of connection of the temperature sensor, a warning message appears. In a medium-frequency induction furnace with an end-of-temperature relay, when the temperature exceeds 120 degrees, the relay is activated and stops heating.
(6) Convenient parameter settings. Temperature adjustment range 40 ~ 120 ℃, variable voltage adjustment range 200 ~ 2200 V, constant voltage adjustment range 0 ~ 500 V.
Product Advantages
1. High sensitivity: extremely sensitive to trace amounts of polar impurities (such as acids and colloids produced by aging) in insulating oil.
2. Deep diagnosis of insulation aging: The dielectric loss factor (tan δ) directly reflects the power loss of insulation oil under alternating electric fields.
3. More reliable test results:
Adopting high temperature (such as 90 ℃) testing can truly reflect the insulation performance of the oil at the actual operating temperature of the transformer, eliminating interference such as moisture.
4. Automated operation and high precision:
One click automatic heating, testing, and calculation, displaying results directly.
5. Complies with international standards
The design and testing methods comply with international standards such as IEC and ASTM.
