Insulating Oil Dielectric Strength Tester

Product Overview:

This instrument is a high-accuracy, fully digital industrial device meticulously developed by our company's entire team of scientific research and technical personnel. Based on the national standard GB507-1986 and industry standard DL/T846.7-2004, leveraging our strengths, and through numerous field tests and persistent efforts, it meets diverse user needs with models available in single-cup, triple-cup, and multi-cup configurations. The instrument is easy to operate and features an aesthetically pleasing design. Equipped with fully automated digital microcomputer control, it ensures high measurement precision, strong anti-interference capability, safety, and reliability.

Instrument Features:

1. The instrument uses a high-capacity single-chip microcomputer for stable and reliable operation;

2. A wide-range watchdog circuit is built-in to prevent crashes;

3. Multiple operation options are available, including two national standard methods (GB507-1986 and GB507-2002), industry standard DL/429, international standard IEC156, and custom operations, catering to various user preferences;

4. The oil cup is made of special glass through one-time casting, eliminating interference such as oil leakage;

5. A unique high-voltage end sampling design allows test values to directly enter the A/D converter, avoiding errors from analog circuits and ensuring more accurate measurements;

6. The instrument includes protections against overcurrent, overvoltage, and short circuits, with strong anti-interference capability and excellent electromagnetic compatibility.
