Overview

Overview

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-40kV 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.
