I. Overview

Insulation oil dielectric strength tester is our company's all scientific research and technical personnel, according to the national standard GB507-1986 and the relevant provisions of IEC60156 international standard, give play to their own advantages, after many field tests and long-term unremitting efforts, carefully developed and development of high accuracy, full digital industrial instruments. In order to meet the needs of different users, this series of instruments can be divided into single cup three cups and multiple cup models. The instrument is easy to operate, beautiful and generous in shape. Because of the use of automatic digital microcomputer control, so the measurement accuracy is high, anti-interference ability is strong, safe and reliable. The instrument is powered by lithium battery, and the test is conducted without external power supply.

II.Instrument Characteristics

1. The instrument is controlled by large-capacity microcontroller, which is stable and reliable;

2. The wide range watchdog circuit in the instrument to eliminate the phenomenon of crash;

3. A variety of operation options, the instrument program has GB507-1986, GB507-2002 two national standard methods, industry standard DL / 429, international standard IEC156 and custom operation, there are 10 optional standards, to meet the needs of most international countries;

4. The instrument oil cup is cast with special glass once, eliminating the occurrence of oil leakage and other interference phenomena;

5. The unique high-voltage end sampling design of the instrument allows the test value to directly enter the A / D converter, avoiding the error caused in the analog circuit, and making the measurement results more accurate;

6. The frequency can be set according to customer needs, and converted to 50 / 60 HZ, to meet the needs of different customers;

7. The instrument interior has overcurrent, overvoltage, short circuit and other protection functions, and has a strong anti-interference ability, good electromagnetic compatibility;

8. Built-in lithium battery, no external power supply. Portable structure, easy to move, inside and outside the household to use are very convenient.
