Insulating Oil Dielectric Strength Tester Detailed Description;
I. Instrument Features:
1. The instrument adopts a large-capacity microcontroller, with dual CPU control for stable and reliable operation.
2. A wide-range watchdog circuit is built in to eliminate system crashes.
3. Multiple national standard options: the instrument program includes two national standards (1986, 2002) and custom settings, accommodating diverse user preferences.
4. The oil cup is made of composite material cast in one piece, preventing oil leakage and fragility.
5. The unique high-voltage sampling design allows test values to go directly into the A/D converter, avoiding errors in analog circuits and making measurement results more accurate.
6. Uniform and stable voltage rise speed.
7. Built-in function generator with low distortion of power frequency sine wave and stable frequency, avoiding the influence of grid harmonics on test results when directly using the grid as the booster power supply.
8. The instrument has overcurrent, overvoltage, short-circuit protection, and strong anti-interference capability with good electromagnetic compatibility.
9. Simple operation, large LCD screen, Chinese menu interface.
10. Metal casing, elegant appearance, desktop structure, suitable for both indoor and outdoor use.
