About Megger Transformer Oil Testers
Megger oil testers are instruments designed to assess the quality and integrity of insulating oils used in electrical equipment such as transformers, circuit breakers, and cables. These testers determine the oil?s ability to withstand electric stress, ensuring it remains a reliable insulating medium by identifying contaminants like water, conductive particles, or ageing by-products.
Operation Principle
Megger oil testers typically apply a controlled voltage to an oil sample and monitor its response to assess various electrical properties. E.g For dielectric breakdown testing, the voltage is gradually increased until the oil's insulating properties fail, indicating the maximum voltage the oil can withstand before breaking down. This process helps in determining the oil's suitability for use in high-voltage equipment.
Dielectric Breakdown Voltage Testing
Instruments like the Megger OTS (Oil Test Set) series measure the voltage at which the insulating oil fails electrically, indicating its ability to withstand operational stresses.
Key Functions
Key specifications within the Megger oil tester range include:
- Test voltages up to 60kV, 80kV, or 100kV, depending on the model
- Compatibility with mineral, ester, and silicone insulating liquids
- Transparent, electrically shielded testing chamber with ample visibility
- Configurable test sequences for international test standards like IEC, ASTM, and BS
Notable Features
Selected models feature:
- Automatic voltage application with fast shutdown (<10?s)?for safety during breakdown testing

Applications
Megger transformer oil testers are essential tools for power generation facilities, electrical transmission networks, distribution substations, industrial maintenance, oil analysis laboratories, transformer manufacturing, and high-voltage equipment services. They are used for:
Quality Assurance: Regular testing of insulating oils ensures they meet industry standards and are free from contaminants that could compromise electrical equipment performance.
Predictive Maintenance: Monitoring oil parameters helps in early detection of potential issues, allowing for timely maintenance and preventing unexpected equipment failures.
Safety Compliance: Ensuring the insulating oil's integrity is vital for the safe operation of high-voltage apparatus, protecting both equipment and personnel.
