Main Categories of Oil Testing Instruments
1. Insulating Oil Breakdown Voltage Tester (BDV Tester)
Measures the dielectric strength of transformer oil. This test ensures the oil’s insulation capacity is sufficient to protect high-voltage equipment.
Standards: IEC 60156, GB/T 507
Features: Fully automatic test, programmable settings, built-in printer
2. Insulating Oil Dissipation Factor Tester (Tan Delta)
Analyzes dielectric loss and capacitance, indicating oil aging and contamination.
High precision and temperature-controlled testing
Essential for condition-based maintenance of power transformers
3. Closed Cup Flash Point Tester
Determines the temperature at which oil vapors ignite in a sealed environment.
Standards: ASTM D93, GB/T 261
Critical for safety classification, storage, and transport compliance
4. Open Cup Flash Point Tester
Used for high-boiling point oils and lubricants, simulating open-air conditions.
Standards: ASTM D92, ISO 2592
Common in refineries and heavy machinery maintenance
5. Oil Acid Value Tester
Measures the acidity of oil, a key indicator of oxidation and degradation.
Potentiometric titration method for high accuracy
Widely used in transformer and engine oil testing
6. Pour Point and Cloud Point Tester
Determines the lowest temperature at which oil can flow (pour point) and when wax crystals form (cloud point).
Crucial for evaluating oil performance in cold environments
Used in aviation, rail, and automotive industries
7. Interfacial Tension Tester
Assesses the interfacial tension between oil and water, reflecting oil purity and aging.
Standards: ASTM D971
Helps detect transformer oil deterioration early
8. Water Content Tester (Karl Fischer Method)
Measures moisture content in oil samples with high precision.
Prevents insulation breakdown and corrosion in electrical equipment
9. Viscosity Tester
Analyzes oil flow resistance, a key factor in lubrication performance.
Suitable for gear oils, engine oils, and hydraulic fluids
