Product Introduction

Withstand voltage tests can be divided into AC withstand voltage test and DC withstand voltage test. AC withstand voltage test can be further divided into power frequency, variable frequency, and 0.1Hz ultra-low frequency test technology. Among them, 0.1Hz ultra-low frequency technology is the latest technology and is currently recommended by the International Electrotechnical Commission. The new generation JXCD series microprocessor-based 0.1Hz ultra-low frequency high voltage generator is especially suitable for withstand voltage tests of electrical equipment with large insulation equivalent capacitance (e.g., power cables, power capacitors, large and medium-sized generators and motors). It meets the requirements of the newly issued national electric power industry standard in 2004, "General Technical Conditions for Ultra-Low Frequency High Voltage Generators DL/T849.4-2004".
