ZGF DC Hipot Tester
Product Introduction:
The ZGF DC Hipot Tester is a specialized high-voltage generating equipment designed for on-site testing in the power equipment field. It features reliable protection functions, including overvoltage, overcurrent, and zero-closing protection, and provides accurate 0.75 times output voltage indication for precise measurement and control.
Product Features:
The ZGF Series DC High Voltage Generators offer a compact and reliable solution for on-site testing. Their small ripple coefficient and stable, noiseless voltage output ensure dependable performance. The units feature comprehensive protection functions—including overvoltage, overcurrent, zero-voltage start, and fault protection—with intuitive settings and displays. Voltage and current are digitally monitored, and the built-in 0.75 times voltage conversion function facilitates the testing of zinc oxide arresters. Designed for portability, the generator is structurally compact and lightweight, making it exceptionally easy to carry and deploy in the field.
