VLF withstand voltage tester? Wuhan UHV specializes in producing VLF high voltage generators, with a wide range of product options and professional electrical testing. When looking for VLF high voltage generators, choose Wuhan UHV. 

The VLF withstand voltage tester adopts a series scientific method, which has the advantages of small size, light weight, and easy handling. Especially, this equipment can be used for multiple purposes due to its series connection, making it particularly suitable for XLPE, PE, EPA, RL, PlLC cables and their accessories of medium voltage level, 10kV, and 35kV, and conducting on-site testing. Economical and practical, easy to operate. 

The VLF withstand voltage tester combines modern digital frequency conversion advanced technology, adopts microcomputer control, and fully automates the boosting, lowering, measurement, and protection processes. It can also be manually intervened during the automatic boosting process. Due to full electronicization, it has a small size, light weight, large screen LCD display, clear and intuitive, and printer output test reports. The design specifications fully comply with the power industry standards of "General Technical Conditions for Special Test Instruments for Power Equipment, Part 4: General Technical Conditions for VLF High Voltage Generators", and are very convenient to use. Nowadays, both domestically and internationally, mechanical methods are used for modulation and demodulation to generate ultra-low frequency signals, resulting in non-standard sine wave waveforms, large measurement errors, spark discharge in the high-voltage part, bulky equipment, and high-power high-voltage resistors for discharge shaping in the second and fourth quadrants of the sine wave. Therefore, the overall power consumption of the equipment is relatively high. This product can overcome these shortcomings. 

Characteristics of VLF withstand voltage tester
