WebThe peak pulse current (IPP), is defined as the maximum surge current that can be shunted before the diode itself will overheat and fail. Recall that a surge event can be defined in terms of a maximum current – IPP is a critical value as it determines whether a given diode can absorb that maximum current without seeing any damage. WebLightning return strokes (both 1st and subsequent strokes) have peak current derivatives values of about 100 kA/μsec or about 10 11 A/sec. The voltage produced here will be L x …

WebA surge arrester is a kind of protective device used to limit voltage on equipment by bypassing or discharging surge current. It helps to prevent continued flow, directs them to the ground, and is capable of repeating this process. Surge arresters don’t stop lightning or absorb them. It diverts the lightning and limits the voltage.
