Technical Advantages
Advanced Digital Control: Equipped with 7-inch capacitive touchscreen and high-speed AD acquisition, realizing 10ms fast protection response and 3% measurement accuracy.
Multi-Frequency Adaptation: Supports 0.1Hz/0.05Hz/0.02Hz/0.01Hz four frequencies, matching different test requirements of capacitive loads (max 5.5µF at 0.01Hz).
Energy-Saving Design: Electronic switch technology feeds surplus energy back to the grid, 30% more energy-efficient than mechanical counterparts, with no extra power consumption.
Power Cable Testing: Suitable for 35kV and below XLPE cables, with 3U₀ test voltage setting and 15/60min test time options (meets handover/preventive test requirements).
Generator/Motor Testing: Effective for end insulation defect detection, with phase-by-phase testing method and adjustable test voltage based on rated voltage (Umax=√2×1.2×1.5×U₀).
Capacitor Testing: Stable output for capacitive loads, avoiding waveform distortion with built-in compensation capacitor (0.05µF) for small-capacity samples.
Intelligent Data Management
1.On-Site Data Processing: Auto-saves 64 groups of test data, supporting real-time printing of reports with voltage, current, frequency, and time records.
2.PC Communication: USB interface enables data export and software upgrade, facilitating test data analysis and archive management.
3.Dual-Language Interface: Supports Chinese/English switching, adapting to global user operation habits.
Global Compliance & Certification
1.Complies with IEC standards and Chinese DL/T849.4-2004, suitable for global power industry application
2.RoHS compliant with CE certification, meeting international environmental and safety requirements.
3.Power supply auto-adapts to AC220V±5% 50Hz, compatible with portable generators (≥3kW).
