Switch Analysis
In addition to determining directivity, the algorithm in HDPQ Xplorer firmware is also
able to detect if 3-phase voltage and current waveforms experience a power factor
capacitor switching transient.
There are four transient event types - unipolar, bipolar, ocillatory, or capacitor switch.
For the latter, text detail will include capacitor switch analysis and directivity (when
detected). This capacitor switching event is generated only in 3-phase voltage and
current waveforms.
Event waveform detail 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.
