Product Introduction
The three phase transformer DC resistance tester is the latest generation of transformer DC resistance measurement products, optimized for measuring DC resistance of three-phase winding of large capacity transformers. The DC resistance of the three-phase winding of the transformer can be tested simultaneously. The tap switch can be adjusted directly for the on-load regulator transformer without discharge. The measurement time is one-third of the traditional single-phase measurement, which can greatly shorten the working time and labor intensity. Equipped with the touch screen, large, clear and intuitive, easy to operate, compared with the previous generation of products, its range is increased to 20k, performance and functional parameters are comprehensively improved. Can test main and match transformers. It is equipped with a panel printer and large capacity non-volatile memory, which can store and print measurement results conveniently. The test data is stable, fast, and repeatable, which is the best choice for on-site measurement of transformer DC resistance. It is a new generation of rapid tester that integrates the functions of magnetic aid test, three-phase test, and demagnetization. It is an ideal equipment for measuring the DC resistance of large power transformers.

Product Feature And Application
1, All the high and low voltage current potential test lines are connected to the transformer at one time, and there is no need to reverse the test line during the test process;
2, For the winding test of the star connection method, the instrument can test the resistance of A0, B0, and C0 phases in the way of a three- phase simultaneous test to save the test time.
3, Three-phase five-column low-voltage internal Angle transformer low-voltage test, the instrument adopts the method of automatic magnetic aid, faster than the direct use of large current test speed;
4, Display and print all the test data of the high and low voltage winding of the transformer, and automatically calculate the three-phase unbalance degree, but also print and convert to the resistance value at rated temperature;
5, In three-phase test, A0 data is tested first, and repeated phase test at the same time solves the problem that the neutral lead line resistance cannot be tested in three-phase test at the same time, and the test data is closer to the single-phase test value;
6, It has a perfect anti-potential protection function.
7, Can permanently save 200 test data (expandable), also can use USB storage data to facilitate the user to import the computer processing;
8, wide temperature, high precision, shockproof, anti-interference, easy to carry.
