Audited Supplier This XHZ1340A transformer DC resistance tester is a new generation of rapid tester that integrates the magnetic test, three-phase test and degaussing functions. It is an ideal device for measuring the DC resistance of large power transformers.
Connect the high and low voltage current potential test wires to the transformer at one time, and there is no need to reverse the test wires during the test;
For the winding test of star connection, the instrument can test the resistance of A0, B0, C0 phases by three simultaneous tests, saving test time;
In the low-voltage test of the three-phase five-column low-voltage internal corner-connected transformer, the automatic magnetic assist method is adopted inside the instrument, which is faster than the direct high-current test;
Display and print all the test data of the transformer's high, medium and low voltage windings, and automatically calculate the three-phase unbalance degree, and can also print the resistance value converted to the rated temperature;
In the three-phase test, test the data of A0 first, and then test at the same time, which solves the problem that the resistance of the neutral point lead wire cannot be tested during the three-phase test, and the test data is closer to the single-phase test value;
It has a perfect back-EMF protection function;
The instrument can store 200 pieces of test data permanently (expandable), and it can also use the USB flash drive to store the data to facilitate the user to import it into the computer for processing;
The instrument has the characteristics of wide applicable temperature, high accuracy, shockproof, anti-interference, and easy to carry.
