3 phase DC resistance tester

ZZS-10A DC resistance tester is designed for testing high capacity transformers. The DC resistance of three-phase winding of transformer can be tested simultaneously.

Feature
1.For the Y connection transformer with a neutral lead, when test winding resistance, it can test
resistance of A0,B0,C0 three phase simultaneously, to save test time. Test A0 firstly, then test 3
phase simultaneously, which solve the problem that the neutral lead can’t be tested when 3 phase
tested simultaneously. Make the test data close the single phase test data.
2、for Y type and △ type winding，it can carry out three-phase automatic test and calculate the
three-phase unbalance rate；
3、It has the function of magnetic excitation test and demagnetization (optional) to meet the needs of
field test.
4、The instrument has a variety of protection functions such as anti-electromotive force protection,
break line protection, power off protection.
5、Wide test range, up to 200Ω, high accuracy
6、Power-free clock and date display; local storage and USB storage, local storage can store 200 test
data; The disk storage data format is Word format, which can be edited and printed directly on the
computer.
7、Thermal printer printing function, fast, silent;
8、Small size, light weight, easy to carry and use
