IIJ-II-100 Breakdown Oil Tester

IIJ-II-100 Breakdown Oil Tester is a professional, high-precision instrument designed to measure the dielectric breakdown voltage of insulating oils, primarily used in electrical power systems. It is a crucial device for assessing the health and quality of insulating oil in high-voltage equipment, helping to prevent electrical failures and ensure operational safety. With WEINENG IIJ-II-100 Breakdown Oil Tester, it is a best helper for our ZYD Double Stage Transformer Oil Processing Machine, IIJ-II-100 Breakdown Oil Tester could help you check the oil breakdown results after oil filtration.

Key Functions

• Dielectric Strength Measurement: Its primary function is to determine the voltage at which the insulating oil breaks down (fails electrically) under controlled test conditions. This value, measured in kilovolts (kV), is a direct indicator of the oil’s ability to withstand electric stress.
• Oil Quality Assessment: By measuring the breakdown voltage, the tester effectively evaluates the presence of contaminants such as moisture, solid particles, and soluble polar compounds, which significantly degrade the oil’s insulating properties.
• Data Management: Modern versions often feature data storage, allowing technicians to record and track the test history of oil samples from specific transformers or circuit breakers over time.
• Automatic Testing Cycle: Many models automate the entire test process: stirring the sample, applying the rising voltage, detecting breakdown, and safely discharging the circuit after breakdown, ensuring consistency and repeatability.

Product Features

• High Accuracy & Reliability: Utilizes precise voltage measurement circuits and high-quality components to ensure accurate and repeatable results.

• Safety Interlocks: Equipped with safety covers and interlock systems that automatically cut off high voltage when the test chamber is opened, protecting the operator.

• User-Friendly Interface: Features a clear digital display (often an LCD screen) showing the breakdown voltage, test parameters, and results.

• Automatic Stirring: Includes a built-in magnetic stirrer or motorized stirrer to homogenize the oil sample before and during testing, ensuring a representative sample is tested.

• Compliance with International Standards: The instrument is typically designed to comply with key international test standards such as ASTM D877 and IEC 60156, ensuring that test procedures and results are globally recognized.

• Robust Construction: Built with durable materials to withstand the rigors of a laboratory or field service environment.
