VIND-JJC-80 Transformer Insulating Oil Dielectric Strength Tester – Automated High Voltage Breakdown Voltage Analyzer
Product Details：
The VIND-JJC-80 is a high-precision, microprocessor-controlled testing instrument designed to measure the dielectric strength (breakdown voltage) of insulating oils. Engineered in strict compliance with international standards, this device ensures the safety and reliability of power equipment by accurately assessing the insulating properties of transformer oil and other dielectric liquids.
Featuring a robust standalone design and an intuitive LCD interface, the VIND-JJC-80 automates the entire testing process—including voltage boosting, stirring, settling, and data calculation. Its advanced "SLX" oil cup structure allows for precise electrode gap adjustment, ensuring repeatable and accurate results for laboratories, power plants, and refineries.
Key Features
Multi-Standard Compliance: Pre-programmed with four standard test procedures to meet GB/T 507, DL 429.9, IEC 156, and customizable user-defined protocols.
Fully Automated Operation: The microprocessor controls the entire workflow: automatic voltage rise, magnetic stirring, static settling, breakdown detection, and voltage return-to-zero.
Advanced Data Management: Capable of storing up to 500 previous test results. Includes an integrated thermal printer for immediate on-site reporting of breakdown voltages and test cycles.
Precision Control: Utilizes a uniform voltage ramping method at accurate 50Hz frequency. Features an automatic magnetic stirrer to eliminate oil bubbles and inhomogeneity before testing.
High Safety Standards: Equipped with comprehensive protection against over-voltage, over-current, and limit switches to ensure operator safety.
User-Friendly Interface: A 128x64 graphical LCD displays real-time voltage, status, and operation prompts, making the device easy to operate.
