I.Overview
Hz-139s three-phase high-current tester adopts aluminum alloy chassis, PC panel,
beautiful appearance;High quality ring lifter is adopted, with large output capacity, small
volume and light weight.It is controlled by ARM chip and adopts large LCD screen to
display the primary current and fixed voltage value at the same time.It protects itself
when it's overloaded.It is intuitive and easy to read;With three - phase voltage output,
automatic electronic protection function.It is mainly used in the primary loop channel test
of three-phase system, and can also be used in CT variation-ratio test and occasions
where large current output is required for contact resistance.
