Spikes The Spikes counter should be understood as increase of the RMS value of the line-to-line voltage above the
set V Spike Threshold threshold for less than 40 ms (short time voltage spike).
The counter is available in the two submenus Counters - Day -1 and Counters - Cumulative (previous day or
cumulative)
NOTE: Since the counter is based on the RMS value calculation, two rapid voltage spikes of
equal duration may be evaluated differently, depending on their amplitude:

Sags Certain counters relating to sags are available in the Counters - Day -1 and Counters - Cumulative submenus:
Counters

Sags Short
Sags Middle
Sags Long
The count refers to the reference menu interval (previous day or cumulative)
NOTE: since an event may fall under more than one category, only the counter of the main
type (Long > Middle > Short) is increased
