The Tettex 2293 from Hipotronics incorporates a fast and highly advanced procedure to measure winding resistance. A simple one-time-connection system, together with the simultaneous winding magnetization method, drastically reduces measuring time.
The simultaneous winding magnetization method guarantees fast and reliable measurements, even on large power transformers with delta windings on the low-voltage side, where stable measurements can be seldom reached, using traditional winding resistance measurement instruments. In addition, the new demagnetization function eliminates the magnetic remanence in the core after the application of a dc voltage. The full graphical interface with a 7-inch touchscreen guides the operator through the test procedure. The unit visualizes each test cycle and displays the results graphically or in list format.
