Overview
AST220KV/3MA DC High Voltage Generator is mainly suitable for conducting DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide lightning arresters, power cables, transformers, circuit breakers, generators, etc. in power departments, industrial and mining, metallurgy, steel and other enterprises.
Product Details
AST220KV/3MA DC High Voltage GeneratorIt is mainly suitable for conducting DC withstand voltage tests or DC leakage current tests on high-voltage electrical equipment such as zinc oxide lightning arresters, power cables, transformers, circuit breakers, generators, etc. in power departments, industrial and mining, metallurgy, steel and other enterprises.
By using AIPWM technology, the inaccurate linearity of PWM technology has been adjusted, resulting in a significant improvement in instrument accuracy.
AST220KV/3MA DC High Voltage GeneratorThe use of AI technology to set overvoltage protection and overcurrent protection has replaced the problem of digital dial switches only being able to set voltage values, not current values and voltage drift. It has added AI fully automatic zinc oxide lightning arrester measurement, automatic voltage withstand test function, and can directly print and save test reports, retaining manual mode.
Product nickname: DC High Voltage Generator, DC High Voltage Generator, High Voltage Generator, Medium Frequency DC High Voltage Generator, Portable DC High Voltage Generator, ZGF DC High Voltage Generator, Power Frequency High Voltage Generator, High Voltage Generator DC High Voltage Generator.
