What it represents
An inbound-energy qualifier identifies energy entering a represented device or system. Energy is shown entering the represented boundary in the documented mode. The source may be the grid, a generator or another system interface.
Identify the receiving device and the source path without confusing them with the diagram’s current-reference arrows. Capacity and energy limits remain in the equipment and operating schedules.
How to read it
- Name the receiving boundary and the energy interface.
- The qualifier does not supply a power value or establish an import/export limit.
Information to show or reference
- Identify the associated device, circuit or diagram boundary.
- Name the receiving boundary and the energy interface.
- Cross-reference the equipment data, terminal mapping or operating-state legend needed to interpret the form.
A distinction that matters
The qualifier does not supply a power value or establish an import/export limit.
