10.3.5 Recorded data
Besides counter increments, the information required for a later fault analysis is stored
after a valid voltage variation is detected.
Recorded data information
When voltage variation starts, the phase current magnitudes preceding the activation
moment are stored. Also, the initial voltage magnitudes are temporarily stored at the
variation starting moment. If the variation is, for example, a two-phase voltage dip, the
voltage magnitude of the non-active phase is stored from this same moment, as shown
in
Figure 369. The function tracks each variation-active voltage phase, and the
