Interramp impact pressure tester(I. E. digital program-controlled interphase tester) can efficiently and non-destructively perform electrical tests on components of wire loop winding. The principle is to apply the same pulse voltage to the standard coil winding and the tested winding, and compare the transient waveforms of the two to test the quality of the tested coil. The transient waveform is also the waveform of the attenuation oscillation that occurs in the coil. It can also determine the inductance of the winding, the quality factor, the difference in the number of windings, and the short-circuit between turns. In the case of iron cores, it can also be judged. The difference in material quality, etc.. In the case of high voltage Pulse, the occurrence of Corona discharge can also judge the poor insulation. In short, the various elements of the marking coil quality can be checked in a very short time.

The instrument quantifies the various parameters of the waveform through microcomputer technology, and then uses the intuitive waveform and data to display and judge. The operation is simple, the judgment is accurate, and the degree of automation is high.

The HYG-2670A interramp impact pressure tester is centered on a microcomputer, which controls the high voltage pulse generator to apply a very short time high voltage pulse to the coil; The capacitance of the coil under the action of the pulse and the instrument produces a free attenuation oscillation, and then the oscillation waveform is processed by the PLD-controlled high-speed A/D acquisition and sent to the microcomputer, and the microcomputer performs time, Corona, area, and other parameters. Operation, The results are stored in electronic memory and displayed on the LCD screen with intuitively understandable text, data and graphics; In order to ensure the authenticity of the waveform recurrence. And according to the conditions set by the user, the qualified or unqualified person is treated with alarm.
