The interturn impulse voltage tester is based on the basic principle of detecting the symmetrical balance of the impedance of the tested object. The equivalent overvoltage simulation test of the motor and transformer windings is carried out by using the shock wave comparison method with high frequency and high voltage pulses. The oscilloscope of the instrument is used to observe the waveform comparison and analysis, which can directly and quickly test the interturn short circuit and various impedance imbalance faults in the windings.

?To do the winding of the transformer, electrical coil winding of the turn insulation monitoring and testing need to use the turn impact voltage tester, at this time there will be consumers asked, this high voltage equipment of the test instrument how to use and operate the test? Now let me teach you how to use the impulse withstand voltage tester to do impulse voltage test.

?1. Equipment wiring:

First, ground the ground wire grounding network and the interturn impact voltage tester, and connect the two parts of the impact voltage tester in the direction of the arrow with the connecting wire and fasten the lock. Then the high-voltage test line is connected to the tester and the subject, the foot switch is connected to the control end part of the tester, and finally the power line part of the tester is connected.

2. Test demonstration:

?After the instrument power supply is turned on, first preheat the instrument for five minutes and observe whether the work indicator light is on. If it is not on, press the phase change button to wake up the indicator light. When the work indicator light is on, press the foot switch and adjust the high voltage knob to 2kV. After the judgment is completed, release the foot switch to adjust the high pressure knob to reduce the pressure.

3. Waveform analysis:

?Different subjects are compared with the same operation method. If the waveform does not coincide, it indicates that the subject is unqualified, and the waveform of the short-circuit subject is often a straight line; The waveform of the short circuit between turns is slightly lower than that of the standard subject.

Note: When adjusting the high voltage knob, the foot switch needs to be stepped on to adjust, when the voltage boost can not be stepped on the foot switch for a long time, you need to loosen the step to observe the contact degree of the waveform.

?The above is the use of the interturn impact voltage test tester, generally in accordance with the specification of the instrument operation can basically master the normal use of the instrument, such as big problems can directly consult the relevant technicians of the manufacturer to apply for after-sales!
