Accessories and Consumables
| Accessory | Quantity | Description |
|---|---|---|
| Electrode assembly | 1 | Tungsten steel test electrode + stainless steel rod, compliant with specifications |
| Droplet device | 1 | Ensures precise droplet application, adjustable droplet volume |
| Droplet container | 1 | For test solution, supports accurate droplet control |
| High-precision flow meter | 1 | Ensures uniform and precise droplet volume |
| Gas interface | 1 | For connection to user-supplied gas source (e.g., LPG) |
| Specimen holder | 1 | Supports different shapes and sizes, ensures stability |
| Temperature sensor | 1 | Measures and controls temperature during testing |
Test Principle
The Leakage Current / Tracking Tester applies voltage across the surface of solid insulating materials while dripping a defined concentration of liquid (e.g., NH4Cl solution) between electrodes. The combination of electric field, voltage, current, and droplet count simulates surface tracking and erosion phenomena. The tester measures tracking onset time and damage depth, evaluating the material’s durability and safety in humid electrical environments.
Operating Instructions
Specimen Preparation: Secure the specimen in the holder, ensuring good contact with electrodes.
Parameter Setting: Set droplet interval, voltage, current, and droplet count using the touch screen.
Start Test: Press “Start”; the device automatically initiates droplet application and voltage.
Record Results: The system automatically records all test data during the process.
Test Completion: After testing, the device shuts off voltage, stops droplet application, and exhausts fumes. Results are saved and can be stored for analysis.
Safety Precautions
Ensure the equipment is powered off before cleaning or maintenance.
Avoid touching electrodes and specimen holder during testing to prevent electric shock.
Ensure stable gas connection and shut off gas after testing.
