Fast delivery I 24-hour customer service I customizable Product Introduction HZDP-60kV VLF Hipot Tester targets heavy-duty insulation testing for very high-voltage systems. It supports AC, DC, and ultra-low frequency withstand tests in accordance with international recommendations. Featuring a 7-inch touchscreen, ARM7 single-chip processor, and rapid AD data acquisition, it delivers precise and reliable testing results. Perfect for very high-voltage cables, large industrial capacitors, and oversized generators, it guarantees compliance with national electric power regulations and the 2004 L/T849.4-2004 ultra-low frequency high-voltage generator standards. 4. Voltage positive, negative peak error: <3% 5. Voltage waveform distortion degree: <5% 6. Conditions of use: indoor, outdoor; temperature: -10°C~+40°C; humidity: <85%RH 7. Power supply fuse: See table 3 8. Power Supply: Voltage 220V±5%, 50±5Hz Note: If the portable generator is used for power supply, the generator output voltage and frequency are required to be stable (generally, the power is greater than 3kW, the frequency is 50Hz, and the voltage is 220V±5% • Innovative digital frequency conversion and microcomputer technology, integrating voltage rise, reduction, measurement, and protection. • Fully automated testing for convenience. • Simple to operate: easy wiring and foolproof handling. • Multiple protections: over-voltage and over-current protection at both voltage sides, rapid response <10ms ensures safe use. • Reliable: controller connected to low-voltage side of generator with photoelectric isolation. • High-low voltage closed-loop negative feedback ensures output stability without capacitive rise. • Complete system: capacitive touch screen, Chinese LCD, automatic storage, and printing. • Large range: selectable 0.1Hz, 0.05Hz, 0.02Hz frequencies. • Small, lightweight design suitable for field work.
