FAQ – Transformer Oil Breakdown Voltage Tester
Optimized for Google SEO, targeted at substation operators, power maintenance teams and third-party electrical labs
Q1: What is the main function of this oil breakdown voltage tester?
A: It measures the dielectric breakdown voltage of transformer insulating oil. By testing oil insulation performance, it detects moisture, impurities and oil aging, so as to judge the internal insulation condition of transformers and other oil-filled high-voltage equipment and prevent insulation breakdown faults.
Q2: Why won’t this tester freeze during long-time testing?
A: It adopts professional electromagnetic compatibility (EMC) design. Even in narrow spaces with strong electromagnetic interference common in substations, the system runs stably without crashing, a prominent advantage over traditional CPU-controlled testers.
Q3: How does the instrument guarantee high test accuracy?
A: It uses an electronic inverter sine wave voltage regulator, free from disturbances of grid voltage fluctuation and waveform distortion. Besides, the low-energy breakdown control avoids oil sample contamination, making test results more accurate and repeatable.
Q4: What safety protections are built into the device?
A: Multiple safety protection circuits are equipped. It can automatically cut off high voltage when facing empty oil cup breakdown or deteriorated oil breakdown, fully protecting operators and the host machine against high-voltage hazards.
Q5: What voltage ranges can this model support?
A: Two optional output ranges: 0~80kV and 0~100kV, with a minimum resolution of 0.1kV to meet global standard oil withstand voltage test requirements.
Q6: Can I adjust the voltage rising speed?
A: Yes. Three rising speeds are selectable: 1.0kV/s, 2.0kV/s, 3.0kV/s, complying with IEC and international power testing standards.
Q7: How many repeated tests can be set for one oil sample?
A: The test cycle can be set from 1 to 6 times automatically; the device will calculate the average value after all tests to reduce manual errors.
Q8: What are the specifications of the oil cup?
A: Dual capacity oil cup: 200ml / 400ml. The electrode gap is 2.5mm and adjustable. The oil cup is made of high-strength special material with long service life.
Q9: What is the overall weight and size, is it convenient for field carrying?
A: Net weight is 22kg, overall dimensions: 310×420×360mm. Compact structure, suitable for both laboratory fixed testing and on-site substation mobile inspection.
Q10: What working environment can the instrument adapt to?
A: Operating temperature: 0~40℃; humidity ≤80%RH (no condensation). It fits conventional indoor laboratory environments as well as substation field working conditions.
Q11: Does the tester come with a printing function for test data?
A: Yes. Built-in thermal printer outputs paper test reports directly, convenient for filing, archiving and project record submission.
Q12: What power supply does it use?
A: Standard AC 220V±10%, 50Hz power supply, widely compatible with power grids in most countries.
