The insulation oil dielectric strength tester is a product developed by our company's research and technical personnel. It adheres to the national standard GB 507-1986 and the relevant provisions of the IEC 60156 international standard. Leveraging their expertise and after extensive field tests and continuous efforts, we have developed a high-accuracy, fully digital industrial instrument. To meet the diverse needs of users, this series of instruments is available in single-cup, three-cup, and multiple-cup models. The instrument is easy to operate and features an attractive design. With automatic digital microcomputer control, it offers high measurement accuracy, strong anti-interference capabilities, and safety. The instrument is powered by a lithium battery, allowing tests to be conducted without an external power supply. Instrument Characteristics 1.The instrument is controlled by a large-capacity microcontroller, which is stable and reliable. 2.A wide-range watchdog circuit is integrated into the instrument to prevent crashes. 3.The instrument offers various operational options, including two national standard methods (GB 507-1986 and GB 507-2002), the industry standard DL / 429, the international standard IEC 156, and custom operations, providing 10 optional standards to meet the needs of most countries. 4.The instrument's oil cup is cast from special glass in a single piece, eliminating the risk of oil leakage and other interferences. 5.The unique high-voltage sampling design allows the test value to enter the A/D converter directly, avoiding errors in the analog circuit and resulting in more accurate measurement results.
