VLF is generally considered to be 0.1 Hz and lower, its major application is for testing solid dielectric cable, transformers, motors, generators, switch-gear and other electrical apparatus.
A VLF hipot is just an AC output tester but with an output frequency of 0.1 Hz or lower rather than 50/60Hz. Although the frequency is very low, it is still an alternating current with polarity reversals every half cycle. At 0.1 Hz output, rather than 60Hz, it takes 600 times less current and power to apply an AC voltage to a capacitive load, like a long cable.
FUOOTECH FTAC Series VLF High voltage withstand test of electrical equipment is one of the most important items stipulated in "insulation preventive test". Voltage withstand test can be divided into AC voltage withstand test and DC voltage withstand test, AC voltage withstand test can be divided into power frequency, variable Frequency and 0.1Hz ultra-low frequency test technology, of which 0.1Hz ultra-low frequency technology is the latest technology, is the current international Technology recommended by the Electrical Committee. Our company's new generation series of ultra-low frequency high voltage generator is the latest. The core product independently developed by the United States technology, using 7 inch touch screen, the latest ARM7 microcontroller, high speed AD acquisition. Set circuit, and equipped with background management software.
