I. Overview
Many power systems, railway systems, large-scale petrochemical plants and
enterprises have a lot of electrical equipment whose internal insulation are mostly oil-filled
insulation type, and therefore, test on insulating oil dielectric strength is common and
necessary. To meet the needs of the market, we have developed and produced a series of
insulating oil dielectric strength testers according to national standard GB/T507-2002,
industry standard DL429.9-91 and the latest Electric Power Industry Standard
DL/T846.7-2004 by ourselves. This instrument, by using a single-chip microcomputer as
the core, can operate in full automation with high accuracy, greatly improving work
efficiency and reducing the labor intensity of workers. Moreover, it is small in size and
convenient to carry.
II. Key Function And Feature
1. With a microprocessor, automatically fulfill the withstand voltage test for oil circulation
with a range of 0 ～80KV (including boosting, maintaining, mixing, standing, calculation,
printing and other operations)
2. Display by large-screen LCD and prompt by English menu.
3. 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.
4. Power-down preservation. It can save 100 tested results and displaying current
ambient temperature and humidity.
5. Adopt a single-chip microcomputer to boost the voltage at an even speed. The voltage
is accurate at 50HZ, ensuring the whole process easy for control.
6. Equipped with over-voltage, over-current and limit protections to ensure the safety of
operators.
7. With the function of displaying the measured temperature and system clock.
8. Communicate with computer with a standard RS232 interface.(Optional)

V. Operational Approach
1 Pre pa ration bef or e Test
①Connect the earth terminal (on the right side of the equipment) to the earth wire firmly
before start the equipment.
②Sample the oil according to relevant standard. Adjust the electrode distance inside the
oil cup with standard gauge. Clean the cup according to relevant requirements. Pour the
sample into the cup and close the cap.
③Switch on AC220V power supply after the above items are confirmed, ready for the
test.

an d was h.
3. Oil Cup St orage
Method 1 Fill the cup with good ins ul at ing oi l after the test is finished and
pl ac e it stable.
