Product Description
Oil BDV Tester Introduction:
HJT-A series advanced type fully automatic transformer oil breakdown voltage tester is applied to test the insulating oil's dielectric strength, It widely used in many power systems, railway systems, large-scale petrochemical plants and enterprises,which have a lot of electrical equipment whose internal insulation are mostly oil-filled insulation type.It is designed as per the requirement of National standard GB / T507-2002, industry standard DL429.9-91 and the latest power industry standard DL / T846.7-2004, international standard IEC 156, IEC 60296,ASTM D 1816,etc
Main features:
1. The instrument is controlled by single chip microcomputer with large capacity, and works stably and reliably;
2. The instrument is equipped with temperature, humidity and clock display functions,Customized infrared oil temperature measurement;
3. The instrument is equipped with a wide range of watchdog circuit to eliminate the phenomenon of dead machine;
4. Various operation options. Instrument built-in GB/IEC standard and customized operation, which can adapt to various choices of different users;
5. The instrument oil cup is cast and formed by special glass in one time, eliminating the occurrence of interference phenomena such as oil leakage;
6. The unique high-voltage sampling design of the instrument allows the test value to directly enter the A/D converter,avoiding errors caused in the analog circuit and making the measurement results more accurate;
7. The instrument has internal protection functions such as over current, over voltage and short circuit, and has strong anti-interference ability and good electromagnetic compatibility;
8. Instrument self-analysis function, assist operator to judge sample oil;
9. USB and RS232 interface;
10. Large colorful touch screen;
11. Portable structure, easy to move, indoor and outdoor use is very convenient.
