OTD-B Oil Tan Delta Tester

• Oil cup adopts a three-electrode structure with a 2mm electrode gap, reducing the influence of stray capacitance and leakage on the test results.

• Built-in SF6 gas-filled three-terminal standard capacitor ensures long-term stable accuracy.

• Medium-frequency induction heating combined with PID temperature control provides non-contact, uniform, and rapid heating with precise temperature control.

• Supports empty electrode cup calibration and automatically saves data to ensure accurate calculation of relative permittivity and DC resistivity.

• The AC power supply adopts an AC-DC-AC design, providing strong resistance to voltage and frequency fluctuations.

• The heating furnace is equipped with a temperature limiting relay, which automatically stops heating if the temperature exceeds the limit.

• Large-size LCD touch screen with a clear and intuitive interface, and test results can be automatically saved and printed.

• Built-in real-time clock, and the test time is saved, displayed, and printed along with the results.

• It supports an optional intelligent closed-loop automatic oil draining system, which automatically and accurately drains the oil after testing, ensuring no residue and accurate data.

• With multiple protection functions, including overvoltage, overcurrent, and high-voltage short circuit protection, and automatically cuts off the high voltage and triggers an alarm in case of abnormality.
