The series impulse winding tester, is suitable for motor( three-phase machine), transformer, small inductance coil, micro motor, and other kinds of wire coil measuring. The instrument adopts the computer automatic storage standard sample waveform of setting of test parameters (area, area difference, frequency, corona, inductance) compared with parts being measured automatically, the discriminant conform to the requirements of standard sample, compared with the traditional world exposition graphical observation comparative method, more accurate, more intuitive to test the product quality of small change by the reaction of computer data processing directly.
- Sampling rate 200MSPS-1MSPS adaptive adjustment, observe DUT’ S waveform change in details
- The minimum coil inductance can be tested is 10uH, meet the requirement of most coil test
- Based onARM11+FPGA construction of signal processing module , process speed is rapid
- With mode prediction and signal separation and other digital signal process method, the repeat rate of measurement is high.
- Synchronous measuring coil inductance L, damping ratio, Q value and other parameters, realize coil performance comprehensive analysis
- With corona peak, total amount, discharge times and other quantitative measurement
