VLF Series 0.1HZ Intelligent Ultra Low Frequency High Voltage GeneratorDetailed product description：

The new generation VLF series 0.1Hz intelligent ultra-low frequency high voltage generator overcomes many shortcomings of the first generation mechanical products, with a much higher cost-effectiveness than similar imported products. It is particularly suitable for withstand voltage testing of electrical equipment with large insulation equivalent capacitance (such as power cables, power capacitors, large and medium-sized generators, and motors), and meets the requirements of the newly issued national power industry standard "General Technical Conditions for Ultra Low Frequency High Voltage Generators DL/T849.4-2004".

Characteristics
Advanced technology: adopting digital frequency conversion technology, microcomputer control, and fully automated testing process.  
Easy to operate: simple wiring and convenient operation.  
Comprehensive protection: quadruple protection, quick action (action time ≤ 20ms), safe and reliable instrument.  
Safe and reliable: The controller and high-voltage generator are connected at low voltage, with photoelectric control, ensuring safety and reliability.  
Fully equipped: LCD Chinese character display, automatic storage, and automatic printing.  
Large testing range: Multiple frequency options of 0.1Hz, 0.05Hz, and 0.02Hz, with a wide testing range.  
Small size and light weight: very conducive to outdoor operations.
