This page shows the parameters set before recording voltage anomalies:
Fig. 161: 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. 160).
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
