HSTC waveform viewer navigation
|A||Active window||This window displays a portion of the overall captured disturbance.|
|B||HSTC V1-V4 phase selector||Click to select a single voltage phase V1 through V4.|
|C||Slider control (top and bottom)||Click and drag to focus on an event in the Active window. The values shown in the information panel at the bottom of the screen will update to reflect the new slider positions.|
|D||Scale||Auto generated value based on the magnitude of the detected
NOTE: The color of the text matches the voltage phase selected. For example, blue text indicates HSTC V3 phase has been selected.
|E||Trigger point||The time when the transient thresholds are exceeded.
NOTE: The color of the trigger point indicator arrow matches the voltage phase selected. For example, a red arrow indicates HSTC V1 phase has been selected.
|F||Histogram||The histogram shows the complete captured disturbance. Waveform samples are grouped into bins based on the peak magnitude of the sample.|
|G||Active histogram window||This
window functions as a coarse zoom. Select and drag the window to any
point in the histogram to focus on a specific set of waveform samples.
The waveform samples contained within this histogram window are displayed
in the active window above.
NOTE: The waveform samples in the active window reflect the selected HSTC phase.
The peak magnitude of captured high-speed transients is sorted into three bin thresholds to aid in the classification and analysis of the captured event.
Mag <= 1500 V
Right click in the histogram to set the number of active bins and their corresponding thresholds.
NOTE: The updated threshold settings are used for informational purposes only. They do not change the conditions set to detect transients, nor are they retained when the HSTC waveform viewer is closed.
|I||Trigger timestamp||Timestamp representing the point in time that the transient condition was detected.|
|J||Active window zoom||This
window functions as a fine zoom. Click, hold and drag your cursor
across any waveform portion in the active window.
NOTE: The waveform samples in the active window zoom reflect the selected HSTC phase.
click within the histogram window to view the spectral analysis of
the selected samples.
NOTE: The spectral analysis window reflects the selected HSTC phase.
