This page shows the parameters set before recording voltage anomalies:
Fig. 123: Voltage Anomalies
The following non-modifiable parameters are indicated (as they have been set upon
starting the recording)
Nominal Voltage : nominal voltage
High Voltage : limit high voltage.
Low Voltage : limit low voltage.
VT : transformation ratio of the voltage transformers.
This page also shows the total number of voltage anomalies occurred ( Number of
Anomalies ).
The following keys are active on this page:

The up and down arrow keys move the cursor alternatively on Type or Phase

The F3 and F4 keys (or the MOD(+) and MOD(-) items on the display) enable the user
to filter the anomalies to be selected. It is possible to select All , Up , Down , Int (if the
cursor highlights Type ) and All , Phase1 , Phase2 , Phase3 (if the cursor highlights
Phase )

The ENTER key (or the smart icon on the display) confirms the selection previously
made and displays the table of voltage anomalies.

The ESC key (or the smart icon ) to exit the functions and go back to the “Anomalies”
page (Fig. 122).
5.7.1.4. Spikes (Transients)
This page shows a table containing all of the Spikes, i.e. all of the phenomena associated
to phase voltage characterized by:

Fast variations of voltage waveform slope

Exceedings of a limit threshold defined by the user before recording
