5つの波形比較を提供 | ||
全面積比較 |
When layer short happened, the loss of power on coil increase, the resonance damping coefficient increase, resonance amplitude decrease, the total area decrease. These are the basic parameters we check layer short. By calculating and comparing the deference of area between golden sample and DUT. |
|
微分面積比較 |
Add up the difference between normal wave and DUT wave call “ Area differential”. By calculating and comparing the deference of area between golden sample and DUT. To determine the degree of waveform overlap. |
|
波形比較 | Set a acceptable wave range, if the DUT’s wave is in this range shows “pass” otherwise, “fail” This parameter can judge both amplitude and phase of resonance wave. This can increase the detection capability of layer short. |
|
コロナ比較 | In pulse test, the insulation defect will cause discharge and create corona. This function is able to count the times that corona happened base on the degree of deviation. Detect the discharge phenomenon on the coil. |
|
Flat 比較 |
If the layer short happened, the waveform will tremble. Therefore, the instrument will quantize and compared it. |
