Breakdown Voltage Transformer Oil Testing Equipment High Precision Adjustable Voltage Rise
NSH Insulating Oil Dielectric Strength Tester
I. Description of BDV Tester
NSH NIT series Transformer Oil Breakdown Voltage Tester is fully automatic micro controller based system, completely self-contained, compact and portable giving smooth variable test voltage from 0 to 100 kV for testing the dielectric strength of transformer oil in accordance with all international standards like ASTM D1816/IEC156/IS6792/ ASTM D877/ UNE 21 specifications.
II. Features of BDV Tester
- Easy operation, high autoimmunization (only press button once and all work done automatically)
- Menu management, data input simple and convenient.
- It can store 99 data of oil sampling tests, the test data can be reviewed and printed in 100 years even after power is off.
- The clock in going on after power off.
- The software can be upgrade through RS232 terminal. Test data can be uploaded to PC by RS232 port.
- Strong anti-jamming, high precision testing.
- Small measurement, light weight, and convenient for outdoor operation.

VII. Relative Series:
VFD series: Insulation oil purifier System specialize in purifying branded oil, insulation oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.
TF series: Turbine oil purifier system is particularly suitable for purifying turbine lubricating oil. It also applys to treat hydraulic, coolant oil and other lubrication in which contain large of water, vapor, impurities, sludge, dielectric and colloid. It can eliminate them effectively and efficiently.
LV series: Lubrication Oil Filter System are suitable especially for purifying and restoring hydraulic oil, machine oil, coolant oil and various other lubrication oil.
GER series: Used oil regeneration system is suitable to regenerate used internal-combustion engine oil including diesel engine oil, gasoline engine oil, and used hydraulic oil, other used lubrication oil of machinery.
GED series: it is used to recycle all kinds of waste oil into base oil or diesel oil with high quality.
