Event text
detail:
Capacitor
Switch Analysis
In addition to determining directivity, the new algorithm available in PX5 firmware
V2.0 and higher is also able to detect if 3-phase voltage and current waveforms
experience a capacitor switching event. The result of the analysis is displayed in the
Event Text Detail screen.
Action... Result...
The following transient event
types - bipolar, ocillatory, or
capacitor switch - will include
text detail on capacitor switch
analysis and directivity (when
detected). This capacitor
switching event is generated only
in 3-phase voltage and current
waveforms.
Press Text to display the event
threshold values and textual
summary. The text summary will
display the following
characteristics to describe the
capacitor switching event.
The type of the event whether it
is Normal, Back-to-back, or
Re-strike.
The direction of the probable
location of the switching
capacitor whether it is
Upstream or Downstream
from the monitoring point.
