ZGF Series Intelligent DC Hipot Test Set is widely used in DC high voltage test of electrical equipment such as zinc oxide surge arresters, magnetic blow arresters, power cables, generators, transformers, and circuit breakers.
Overview
Product characteristics and function
● It adopts large-screen dot matrix LCD with man-machine interaction function;
● Fully automatic measurement function for zinc oxide surge arresters with good repeatability and high precision;
● Automatic test function: the test voltage can be preset and the output voltage can be maintained at a constant voltage;
● Automatic timing function: It can preset the boost time of the standard test voltage and automatically timing after the voltage rises to the standard test voltage after finishing timing it automatically drops voltage.
● The high voltage over-voltage setting is adopted with a microprocessor which has high precision and good reliability;
● Retain the manual test mode;
● Data storage function: Instantly capture test parameters and automatically save test results
● According to the theory of electromagnetic compatibility it is combined special shielding multi-stage isolation and grounding protection measures to prevent damage during discharge;
● With print function can print the test result in-time.
