Introduction
The withstand voltage test can be divided into ac withstand voltage test and dc withstand voltage test. The ac withstand voltage test can be divided into power frequency, frequency conversion and 0.1Hz ultra-low frequency test technology, of which 0.1Hz ultra-low frequency technology is the latest technology recommended by the current international electrotechnical commission.
The VLF-90kV is the core product independently developed with the latest technology. It adopts 7-inch touch screen, the latest arm7 single chip microcomputer, high-speed ad acquisition circuit, and is equipped with background management software. Adopting 0.1Hz VLF withstand voltage test technology, equivalent to the power frequency operating environment of cables, improving portability and testing efficiency, ushering in a new era of cable withstand voltage test.

Presenting the VLF-90kV Portable Big LED Screen VLF Hipot Test Set Voltage Frequency Tester, a sturdy and product this might be versatile for high voltage assessment in an amount genuine of systems. Developed by the name brand celebrated, this assessment gear boasts performance quality dependable that guarantees result maximum.
This technique comes insurance firms a large and display obvious is LED provides data evaluation easy-to-read. The screen shows information such as voltage, regularity, leakage present, and angle duration other individuals. The Tanbos screen this is LED backlit, that means it is noticeable even yet in low light conditions.
The Tanbos VLF-90kV Portable Big LED Screen VLF Hipot Test Set Voltage Frequency Tester is crafted for portability, to be able to check always systems that could be areas electric different. The lightweight and design this is lightweight that this method can squeeze into a particular area small such as a toolbox or simply just trucks and car’s trunk. Moreover, the handle this will be base most ergonomic is wheeled that it's a task simple go around while maintaining safety during evaluation procedures.
This Tanbos product normally engineered for durability, combined with casing this can be outside through the robust and item heat-resistant shall withstand environments harsh. The casing protects the sun and rain interior damage during transport or used in commercial settings.
The Tanbos VLF-90kV Portable Big LED Screen VLF Hipot Test Set Voltage Frequency Tester is optimized for high voltage assessment, insurance coverage organizations a manufacturing voltage just as much as 90kV and a regularity of 0.1 Hz. A protection is roofed by the test set this is important that instantly stops the ensure it comes down right down to customer or simply just the apparatus that you discharge the item to avoid dilemmas whenever.
This process typically a piece of cake to arranged and run, insurance policy companies a control simple enough that allows users to improve the voltage regularity and level. The panel comes with an emergency end switch and a test button that initializes the testing procedure
