Breakdown voltage / dielectric strength is an important index to assess the electrical strength of insulating liquids, and it is also a scale to measure the withstand voltage ability of insulating liquids in electrical equipment. This index reflects whether there are moisture, impurities and conductive particles in the oil, and the severity of their impact on the performance of insulating liquids. HK-JYY-80 Automatic Oil Breakdown Voltage Tester is designed according to the national standard GB/T507－2002 Insulating liquids--Determination of the breakdown voltage at power frequency and DL/T 429.9-91 Insulating liquids -- Determination of dielectric strength. It has the features, such as intuitive display, easy operation, automatic measurement, fault self-diagnosis and self-treatment. It is designed based on our own strong and powerful technique force and passed 10 years experience on users’ site. It is widely used in power, petroleum, petrochemical and other fields.

◆Intelligent display and touch screen.

◆With automatic detection and calibration function of the power supply and frequency.

◆With the functions of automatic power-off and fault self-diagnosis functions in case of cover opening, over-voltage and over-current to the safety and reliability of use.

◆ The voltage-rise speed, test times and standstill time can be set. The buzzer will ring after the test.

◆ With automatic stirring function to eliminate the uneven and bubble of oil sample.

◆ The Ethernet port (which is accessible to the LIMS system) and USB port are standard. The RS-232 serial port is optional.

◆ The ball cover electrode is standard, and the circular electrode and spherical electrode are optional, which can meet the different requirements of users.
