The KDJJC-80KV Three-Cup Insulating Oil Dielectric Strength Tester, also known as the Three-Cup Insulating Oil Withstand Voltage Tester, is a high-accuracy, fully digital industrial instrument developed by our company's entire team of scientific research and technical personnel. It was designed in accordance with the relevant provisions of national standards GB507-86 and industry standards DL-474•4-92, DL/T596-1996. After numerous on-site tests and long-term continuous efforts, this advanced tester has been meticulously developed. The instrument is simple to operate, aesthetically pleasing in design. Due to the use of fully automatic digital microcomputer control, it features high measurement accuracy, strong anti-interference capability, and safety and reliability.

1. The instrument uses a large-capacity microcontroller for control, ensuring stable and reliable operation.

2. The instrument features temperature and humidity display as well as clock functionality, and includes a grounding alarm to alert users to safety precautions.

3. The instrument is equipped with a wide-range watchdog circuit to prevent system freeze.

4. Multiple operation options are available; the instrument program includes both GB1986 and GB2002 national standard methods and allows for custom operations, catering to various user needs.

5. The oil cup of the instrument is made from special glass in a single casting process, eliminating issues such as oil leakage and other disturbances.

6. The instrument’s unique high-voltage end sampling design allows test values to directly enter the A/D converter, avoiding errors that could occur in analog circuits, thus making measurement results more accurate.

7. The instrument has internal functions for overcurrent, overvoltage, and short-circuit protection, and it possesses strong anti-interference capabilities with good electromagnetic compatibility.
