Insulating oil in electrical power apparatus serves two primary roles, as an insulator and a coolant. As an insulating liquid, oil's most important property is a high dielectric strength and as a cooling liquid, a low viscosity is paramount. The principal nemeses of insulating oil are oxidation, contamination (particularly moisture, which tends to lower the dielectric properties of insulating oil), and excessive temperature. These enemies are managed through design, regimented installation processes and prudent operation of the oil-filled power apparatus. At all stages of a power asset's life, testing must be conducted to evaluate the condition of the insulating oil. In fact, for some assets, it can be argued that the oil is tested more frequently than any other component. Complies with ASTM D877 D1816 Standard

1. With a microprocessor, automatically fulfill the withstａnd voltage test for oil circulation with a range of 0～80KV.

2. Simple operation. The machine will automatically complete the withstａnd voltage test on one cup of sample oil after simple setting by the operator. Breakdown voltage value of 1 to 9 times and recurrent times will be automatically saved. After the test, the thermal printer will print each breakdown voltage value and average value.

3. Power-down preservation. It can save 100 tested results and displaying current ambient temperature and humidity.

4. With RS232 interface.

Maintenance

1. This equipment shall not be exposed in moist environment.

2. Keep the oil cup and the electrodes clean. Fill the cup with fresh transformer oil for protection during its idle. Check the electrode distance and check the tightness between the electrode tip and electrode bar screw thread before the cup is used again.
