There is a large number of electrical equipment in the power system, railway system and large petrochemical plant mines and enterprises, their internal insulation is mostly oil-filled insulation. The dielectric strength of insulating oil is a mandatory routine test. In order to meet the needs of the market, our company developed and produced a series of dielectric oil dielectric strength testers according to the IEC156 standard" Insulating oils-determination of dielectric strength" and national industry standard DL-474·4-92DL/T596-1996" Preventive test code for electric power equipment".

This instrument takes the single-chip microcomputer as the core, realizes all the automation of the test, has high measurement precision, greatly improves the work efficiency, and greatly reduces the labor intensity of the staff. At the same time, the instrument has a compact appearance and is convenient to carry.

● It adopts a microprocessor to automatically complete the operations of boosting, holding, stirring, static, calculating, printing, etc., and can perform oil circulation withstand voltage test in the range of 0-80 kV.
● The oil cup of the instrument is formed by one-time casting of special glass, which prevents interference such as oil leakage.
● The unique high-side sampling design of the instrument allows the test value to enter the A / D converter directly, avoiding errors caused in the analog circuit, and making the measurement results more accurate.
● Instrument test execution standards include industry standards, national standards and foreign standards, and the operation is simple and convenient.
● With over-voltage, over-current, limit and other protection to ensure the safety of operators. And has strong anti-interference ability and good electromagnetic compatibility.
