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

369. The function tracks each variation-active voltage phase, and the

Power quality measurement functions

A) Three phase mode

B) Single phase mode
