VLF Hipot Test Set-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
The ultra-low frequency high-voltage generators feature a 7-inch touch screen, high-speed AD acquisition circuit, and advanced production technology. Key features include:

High intelligence with digital frequency conversion and microcomputer control for automated testing.
Simple operation with a user-friendly interface.
Comprehensive protection mechanisms for safety and reliability.
Accurate data sampling and wide testing range with multiple frequency options.
Compact and lightweight design for easy transport.
Multi-language display capabilities.

Technical Parameters
The equipment operates on a 220V±5%, 50/60Hz power supply, with a measurement accuracy of 3% and a voltage waveform distortion of ≤5%. The working environment ranges from -10°C to +40°C with humidity ≤85%RH. Various models are available with different rated voltages and load capacities, each with specific power requirements and weights.

Performance Comparison
Compared to other voltage withstand testing equipment, the 0.1Hz ultra-low frequency test offers advantages in equivalence, insulation destructiveness, operation safety, and ease of wiring. It is also lighter and smaller in size compared to power frequency and frequency withstand voltage equipment.

Conclusion
The VLF Hipot Test Set is a cost-effective, reliable, and advanced solution for high-voltage testing, suitable for a wide range of applications in the power industry.
