HZJQ-N1B Portable Transformer Oil Breakdown Voltage Tester BDV Test Device
Many power systems, railway systems, large-scale petrochemical plants, and enterprises use a significant amount of electrical equipment, the internal insulation of which is mostly of the oil-filled type. Therefore, testing the dielectric strength of insulating oil is both common and necessary. To meet market demand, we have developed and produced a series of insulating oil dielectric strength testers in accordance with national standard GB/T507-2002, industry standard DL429.9-91, and the latest Electric Power Industry Standard DL/T846.7-2004. This instrument, which uses a microcontroller as its core, operates fully automatically with high accuracy, significantly improving work efficiency and reducing labor intensity. Moreover, it is compact and easy to carry.
HZJQ-N1B Portable Transformer Oil Breakdown Voltage Tester BDV Test Device
Products Description
I.Key Function And Feature
1.With a microprocessor, the instrument automatically performs the withstand voltage test for oil circulation, with a voltage range of 0–100 kV (including boosting, maintaining, mixing, standing, calculation, printing, and other operations).
2.Displayed on a large-screen LCD with English menu prompts.
3.Simple operation: the machine automatically completes the withstand voltage test on a sample of oil after simple setup by the operator. Breakdown voltage values (1 to 6 times) and the number of recurrent tests are automatically saved. After the test, the thermal printer prints each breakdown voltage value and the average value.
4.Power-down protection: it can save up to 100 test results and display the current ambient temperature and humidity.
5.Uses a microcontroller to boost the voltage at a constant rate. The voltage is accurate at 50 Hz, ensuring that the entire process is easy to control.
6.Equipped with over-voltage, over-current, and limit protections to ensure operator safety.
7.Displays the measured temperature and system time.
8.Can communicate with a computer via a standard RS232 interface (optional).
