DC Hipot Tester 30kV/10A HMZGF

Product Description:

Reliable High-Voltage Testing with Precision and Protection

The HMZGF-30kV/10A DC Hipot Tester is a cutting-edge DC high-voltage generator designed for precise insulation and leakage current testing across a wide range of electrical equipment. Ideal for use in power utilities, research institutions, railway systems, power plants, and chemical facilities, this compact and efficient tester delivers reliable performance in high-voltage environments.

With advanced APWM technology, the HMZGF ensures exceptional linearity and a ripple factor of less than 0.5%—enhancing the accuracy of your results. Its AI-enabled interface allows easy configuration of over-voltage and over-current protection, while features like segmented timing, calendar functionality, and a 75% VDC-1mA zinc oxide arrester testing mode offer unmatched usability and flexibility.

Whether you're testing power cables, transformers, switchgear, or surge arresters, the HMZGF series provides dependable results in challenging field and lab conditions.
