HZYDP-30kV Very Low Frequency VLF AC Withstand Voltage Test Machine
Overview
The high-voltage withstand test of electrical equipment is one of the most important items specified in the Preventive Test of Insulation. The withstand voltage test can be classified into the AC withstand voltage test and the DC withstand voltage test. The AC withstand voltage test can also be divided into power frequency, frequency conversion and 0.1Hz ultra-low frequency test technologies. The 0.1Hz ultra-low frequency technology is the latest technology and is the technology recommended by IEC (International Electrotechnical Commission) at present. The new generation of VLFS series microcomputer type 0.1 Hz ultra-low frequency high-voltage generators are core products independently developed by FARSEE,they overcome many shortcomings of mechanical domestic products, and its cost performance is much higher than the similar imported products. It is particularly suitable for the withstand voltage test of electrical equipment (e.g.: power cables, power capacitors, large- and medium-sized generators and motors, etc.) with large insulation equivalent capacitance, and it meets the requirements of the electric power industry standard General Technical Specification of Ultra-low Frequency High-voltage Generator DL/T849.4-2004 newly issued by the country in 2004.
