Overload Map Panel

The Overload Map panel displays a selected transformer's overload percentage over time. The transformer rating is the highest value that is non-overloaded. The data can be viewed in chart (default) and grid formats.

Note: The Overload Map Panel is available through the Distribution Planning and Operations module when displaying transformer data.

  • Chart view is the default view of the Overload Map panel data. The vertical axis (y-axis) represents the hours during a day, and the horizontal axis (x-axis) represents calendar days.

    Note: Boundary conditions can be configured.

The transformer's calculated percentage overloaded values are charted throughout this graph using the following color sequence:

  •  Green: Not overloaded, or 0–100% of capacity.
  •  Yellow (Warning): Overloaded (101–165% of transformer rating).
  •  Red (Critical): Greatly overloaded (greater than 165% of transformer rating).
  • White: Indicates missing data.

The value of the percentage overloaded along with the date and time appears when you hover the mouse over a cell.

Note: To view the chart data in a grid format from the chart view, click the grid view icon.

  • Grid view displays Overload Map panel data in a table format.
