Impedance timeline tab

The Impedance Timeline chart displays detailed information about the selected service point's impedance calculations during the selected date range.

• Clicking data layers shows or hides the data types on the chart. The following data layers are available:

  • Impedance threshold value. A configurable parameter. This value is a threshold above which an alarm is sent from the High Impedance Detection agent. This value is configured at the agent level and is sent with each message. This value appears in the Alarms card in the Z Base (mΩ) column. The default value is 200mΩ.

  • Phases. The impedance measurements per-phase. Hovering over a phase in the key highlights the plotted data points in the time line for that phase.
