Overview Many power systems, railway systems, large-scale petrochemical plants and enterprises have a lot of electrical equipment whose internal insulation are mostly oil-filled insulation type, and therefore, test on insulating oil dielectric strength is common and necessary. To meet the needs of the market, we have developed and produced a series of insulating oil dielectric strength testers according to national standard GB/T507-2002, industry standard DL429.9-91 and the latest Electric Power Industry Standard DL/T846.7-2004 by ourselves. This instrument, by using a single-chip microcomputer as the core, can operate in full automation with high accuracy, greatly improving work efficiency and reducing the labor intensity of workers. Moreover, it is small in size and convenient to carry. Major Technical Indicators 1. Output voltage: 0-100KV (optional) 2. Voltage distortion rate: 3% 3. Voltage raising speed: 0.5-5 KV/S (adjustable) 4. Standing time: 15min (adjustable) 5. Boosting interval: 5 min (adjustable) 6.Boosting frequency: 1-9 time(s) (optional) 7. Booster capacity: 1.5KVA 8.Measuring accuracy: ±3 9. Supply voltage: AC220V ±10% 50Hz±1 Hz 10. Power: 200W 11.Applicable temperature: 0-45 12.Applicable humidity: 75%RH 13. Overall dimension: 465 385 425

Scope This equipment according to GB/ T507 and industry standards DL429.9 national standard GB designed and manufactured, using a special software and hardware anti-jamming technology, can work in strong magnetic field environment, widely used in electricity, oil and scientific research departments . Features 1. The instrument uses a microprocessor, three cups of whole, auto-complete boost, hold, stirring, static discharge, calculate, print and other operations, oil circulation pressure test can be carried out within 0-80KV range. 2, large-screen LCD, English menu, easy to operate. 3, this instrument is simple to operate, the operator simply simple setup, the instrument will automatically complete the 1-3 oil sample pressure test in accordance with the setting. Each oil sample, each cycle of breakdown voltage and frequency are automatically stored, after completion of the test, a thermal printer can print out the voltage value of each oil sample breakdown various times and average. 4, retentive, it can store 100 test results and can display the current ambient temperature and humidity. 5, using SCM control uniform boost, voltage frequency accuracy of 50HZ, making the entire process easy to control. 6, overvoltage, overcurrent, limit and other protection to ensure the safety of the operator. 7, having a temperature measuring and display function displays the system clock. Technical Parameters 1, the test voltage: 0-80KV (optional) 2, the voltage distortion:

We has developed DST Insulating Oil Dielectric Strength Tester according to International standard IEC156, which is developed especially for measurement of insulating oil breakdown voltage. The dielectric breakdown is an indication of the oil ability to withstand electrical stress. The oil sample is placed in a test cup and an AC voltage is impressed on it. The electrodes are two discs, exactly 1 in. in diameter and placed 0.10 in. apart. The voltage is raised at a constant rate, until an arc jumps through the oil between the two electrodes. The voltage at which the arc occurs is considered the dielectric strength of the oil. DST automatic Insulating Oil Dielectric Strength Tester is unique in the market due to its functionality and the excellent user benefit in comparison to costs. The transformer oil tester provides delivers clear and reliable measurement results. It is no longer necessary to send samples to the laboratory. Environmental and transport influence on the samples are minimized. Due to its design, the tester is particularly handy, easy to operate and especially excellent to use under tough ambient conditions. By proper programming, DST Insulating Oil Dielectric Strength Tester has got functions of auto boosting, step down, stirring, display and print out. Portable type is available for performing both levels of this test in the field.
