Why is there a difference between the entries in the lists “Surge Current List” and “Transient Overvoltage List”?

The sensor of IPCH is designed for a measurement of the change of magnetic field which results from a change in current flow.

Such measurements are shown as events in the surge current list. An additional function of the sensors in combination with the multi-layer PCB board in the IPCH module is a detection of transient overvoltages by capacitive coupling.

This is a mere counting of events without quantitative information about the voltage spikes.
