VLF High Voltage Generator-Catalog

Product catalog summary

Product Introduction
The VLF Hipot Test Set by Wuhan UHV Power Technology Co., Ltd. is designed for high-voltage withstand voltage testing of electrical equipment, a critical component of insulation preventive tests. The test can be conducted using AC or DC methods, with the 0.1Hz ultra-low frequency AC test being the latest and recommended by the International Electrotechnical Commission. This method is particularly advantageous for large and medium-sized generators and motors due to its reduced equipment size and weight, offering a capacity about one-fifth of the power frequency test.

Product Features
1. High intelligence with digital frequency conversion technology and microcomputer control for automated testing.
2. User-friendly operation with a 7-inch LCD touch screen.
3. Comprehensive protection features including overvoltage and overcurrent protection.
4. Safe and reliable with low-voltage connections and photoelectric control.
5. Accurate data sampling directly from the high-voltage side.
6. Fully equipped with automatic storage and printing capabilities.
7. Wide testing range with multiple frequency options.
8. Portable design suitable for outdoor operations.
9. Multi-language display options.

Technical Parameters
The device operates on a 220V±5%, 50/60Hz power supply, with a measurement accuracy of 3% and a voltage waveform distortion of ≤5%. It is suitable for a working environment with temperatures ranging from -10°C to +40°C and humidity ≤85%RH.

Performance Comparison
The 0.1Hz withstand voltage test equipment is compared with other types, showing advantages in equivalence, insulation destructiveness, operation safety, wiring simplicity, and volume and weight. The electronic type offers energy conservation and longer electrical life compared to mechanical types.

Model Specifications
Various models are available with different rated voltages and load capacities, ranging from 30kV to 90kV, with corresponding power requirements and weights for the host and booster components.
