XHZK1620 Low voltage short circuit impedance tester
The short-circuit impedance is an important parameter of the transformer. The short-circuit impedance method is a traditional method for judging the deformation of the winding. According to the provisions of GB1094.5-2003 and IEC60076-5:2000, the variation of the short-circuit reactance is the only criterion for judging whether the transformer winding is deformed or not.
Main features
1.It can measure transformer short-circuit impedance, short-circuit reactance, and three-phase impedance 2.voltage;
3.It can display the voltage, current, power, frequency and other parameters of each test;
4.The measurement can be completed using only the single-phase 220V AC power supply. If no AC power, it can be powered by a small power UPS (online 500VA);
5.The test power supply can be selected from internal power supply and external power supply both: the internal power supply is the instrument working power supply, and the external power supply can be input by the voltage regulator;
6.The wiring operation is simple and convenient. One-time wiring and one-time start can automatically complete the three-phase measurement and directly display the measurement result.
7.The output voltage and output current are automatically controlled by the instrument itself when using the internal power supply, without any external auxiliary equipment;
8.Automatic frequency correction to eliminate errors caused by frequency fluctuations;
9.It can store thousands of measurement results. The instrument has built-in non-power-down memory and can store measurement data for a long time.
10.Large-screen LCD display, Chinese/English menus and operation tips, It's intuitive and convenient;
11.No power down the calendar, clock function.
