1. In the randomly selected interval the differential area between standard coil and test coil is calculated As illustrated by Figure 4 the area difference of A B interval can be calculated to compare the standard wave as Figure 3 and identify the deviation degree The judgment standard is set by percentage Quality products are those with satisfactory calculation results The waveform deviation area reflects the sum of the inductance value and the energy consumption degree For example this judgment method can effectively test the differences of inductance value L H Se E SE E ee Figure 4 Sketch map of area difference comparison 5 IWT Series User s manual 1 7 3 Corona Discharging Amount amp Corona Discharging Number In the process of high voltage pulse testing the test coil may lead to point discharge due to material damage thus generating corona phenomenon in the discharging curves Statistics is made with respect to the frequency of corona generations which can be called as Corona Discharging Number The waveform difference can be basically ignored As illustrated in Figure 5 only the high frequency parts such as Corona Discharging Amount is tested It s also required to test the corona of the waveform in randomly selected interval and judge according to the deviation degree The judgment standard is set by integral value Quality products are those with satisfactory calculation results The testing me
