In power and distribution transformers, switchgears, load changers, cables and circuit breakers etc., insulating oils are very important ingredient and are required with a very high dielectric strength(or breakdown voltage). To test the dielectric strength of insulation oil, PureTech developed HYYJ-502 Insulating Oil Dielectric Strength Tester (transformer oil bdv test kit), which is completely self-contained, compact and portable set.
HYYJ-502 Insulating Oil Dielectric Strength Tester is developed according to the DL/T846.7-2004 "Insulating Oil Dielectric Strength Tester" standard and IEC/ASTM and other international standards. All functions of the instrument are controlled by a rotating mouse. The operation is completed in machine dialogue mode, the built-in EEPROM memory can save 100 sets of test data, and the test results can be printed at any time. It has the advantages of simple operation, powerful functions, stability and reliability, and high degree of automation.
1) 7-inch color LCD touch screen control.
2) The test process fully complies with the requirements of multiple standards of IEC156/IS6792/BS5874, ASTMD1816, ASTMD877, ASTMD1816.
3) The test standard can be selected and set, and the test accuracy is high.
4) Provide PC application software to upload test data to make WORD test report.
5) Automatically complete boosting, holding, stirring, standstill, calculating and printing.
6) Enable to carry out oil circulating withstand voltage test within the range of 0-100kV.
7) Enable to automatically complete withstand voltage for 1~3 oil samples according to the setting.
8) Power-down keeping, enable to store 100 test results.
9) With over-voltage, over-current, limit protection, in order to ensure safety.
