XHZK1620 Low voltage short circuit impedance tester
Product Description
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.
