Insulation Resistance Tester
The insulation resistance tester is used for on-site insulation resistance measurements. The instrument features a built-in negative-polarity high-voltage power supply with high output power and strong load-carrying capacity, making it suitable for measuring the insulation resistance of test specimens with high capacitance, such as power transformers and cables.
Uses
The insulation resistance tester is used for on-site insulation resistance measurements. The instrument features a built-in negative-polarity high-voltage power supply with high output power and strong load-carrying capacity, making it suitable for measuring the insulation resistance of test specimens with high capacitance, such as power transformers and cables.
Function
1. Strong interference resistance. Utilizing digital filtering technology, it can still perform accurate measurements even under 5 mA power-frequency interference current, ensuring stable test data and making it suitable for on-site insulation resistance testing.
2. Built-in negative-polarity high-voltage power supply.
3. High short-circuit current. Not less than 30 mA (this specification far exceeds that of traditional megohmmeters; directly short-circuiting the test voltage or causing a short circuit during measurement may trigger the instrument’s protection mechanism, so special attention must be paid to safety).
4. High load capacity. The high-voltage power supply delivers a current of no less than 6 mA at the 5,000 V voltage level and no less than 3 mA at the 10,000 V voltage level.
5. Rapid discharge. The instrument features an independent discharge circuit; when testing capacitive specimens, it can automatically and rapidly discharge the specimen.
6. High-voltage protection: The output is rapidly cut off in the event of specimen short-circuit, breakdown, or high-voltage current fluctuations.
7. This instrument is equipped with a built-in high-capacity lithium-ion battery pack and supports both AC and DC power sources.
8. Selectable Chinese or English menus; large backlit LCD display
9. Compatible with Bluetooth printers for clear, fast, and silent data printing.
10. Equipped with a USB port for convenient data storage and export.
11. Standard RS485 interface (optional wireless or Bluetooth communication) enables measurement and data processing. Can be integrated into a comprehensive high-voltage test vehicle.
