MEWOI-DH801A series automatic Insulating Oil Dielectric Strength Tester is designed according to international standard IEC60156,national standard GB507-1986, GB507-2002 and industry standard, DL- 474-4-92, the relevant provisions of the DL/T596-1996, with  a lot of field test and long-term unremitting efforts, carefully research and development of high accuracy, fully digital industrial equipment. In order to satisfy the needs of different users, this series of instruments can be divided into single cup three cups and six cup type, etc. The instrument is simple, modeling is beautiful and easy. Adopt fully automatic digital computer control; the measurement is of high precision, strong anti-jamming capability, safe and reliable.


1, The instrument USES large capacity single-chip microcomputer control, stable and reliable in work.

2. The device has wide scope of the watchdog circuit to prevent the death machine.

3. Various operation options, the instrument program has gb507-1986, gb507-2002 two national standard methods, international standard IEC60156, and industry standard DL/T846.7-2004 and customize operation, can adapt to different user's various choices;

4. The instrument oil cup is cast in a special glass, which eliminates the interference phenomenon such as oil leakage;

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

6. The instrument has functions such as over current, overvoltage, short circuit protection, etc., and has strong anti-interference ability and good electromagnetic compatibility

7. Portable structure, easy to move, indoor and outdoor use is very convenient.



The MEWOI-DH801A device is in compliance with international standard IEC60156, China Standard GB507-1986GB507-2002; industry standard DL/T846.7-2016,etc.
