Core Functional Features
- Integrated Capacity & Loss Testing: Combines capacity measurement and characteristic analysis (no-load current, no-load loss, impedance voltage, load loss) in one device. It can determine the actual capacity of various transformers on-site.
- Built-in Power Supply: Eliminates the need for external auxiliary equipment during capacity testing, significantly enhancing efficiency for field operations in remote or outdoor locations.
- Automatic Intelligent Correction: Automatically corrects waveform distortion, temperature, non-rated voltage, and non-rated current based on user-input parameters (e.g., temperature, no-load correction factor) to ensure high accuracy.
- Wide Range & High Precision: Offers a wide measurement range (up to 750V/100A) without the need for manual档位 switching, preventing instrument damage from incorrect gear selection while maintaining ±0.2% precision.
- Performance Level Estimation: Based on measured no-load and load loss data, the system automatically deduces the performance level code for three-phase oil-immersed distribution and power transformers, aiding in rapid on-site assessment.
- User-Friendly Interface: Features a large-screen, high-brightness LCD with adjustable brightness and full Chinese menus, ensuring clear visibility in extreme temperatures or strong sunlight.
