Perform a general trace. This is the same type of tracing that is done before a network calculation. Prior to tracing, the desired scope of tracing must be defined.
Trace
1.Choose Tools > Trace > General Trace.
2.Select trace settings.
3.When all selections have been made, click on Trace only.
4.Select an object in the map or diagram.
5.Point to a relevant object and accept, at which point the trace will start. When the trace is complete, the traced network will light up.
Trace menu settings
Trace method
Select feeding point
|
Marking this option means that the user must mark the point that will be the feeding point of the calculation. If there are network objects that are connected to the feeding point that should NOT be included in the tracing, they must be excluded by marking stop objects that break up the network so that unwanted network parts are not included.
|
Select object
|
Point to any network object within the desired network area when starting the tracing. The extent of the network is primarily controlled by the combination of voltage level and stop type. If several feeding point aspirants are obtained, a specification or stop object must be defined.
|
Select bay in primary substation
|
Point to any network object within/under the desired group when starting the tracing. The highest marked voltage level must be the same as the busbar at the start point of the group, the down side of the station normally. This means that no substation transformers may be included in the trace. The calculation thus includes a group with the connected busbar as the starting point with the desired underlying network, one or more voltage levels.
|
Select bay in Sec. substation
|
Point to any network object within/under the desired group when starting the tracing. The highest marked voltage level must be the same as the busbar at the start point of the group, the down side of the station normally. This means that no substation transformers may be included in the trace. The calculation thus includes a group with the connected busbar as the starting point with the desired underlying network.
|
Select bay in switch station
|
Point to any network object within/under the desired group when starting the tracing. The highest marked voltage level must be the same as the busbar at the start point of the group, the down side of the station normally. This means that no substation transformers may be included in the trace. The calculation thus includes a group with the connected busbar as the starting point with the desired underlying network.

Voltage level
|
Select the voltage levels to trace. Voltage level interacts with Stop types and Tracing method. If the highest voltage level is 20,000 kV and Tracing method Select object are marked, a tracing stop suggestion, Rail 20,000 kV, will be obtained.
|
Usage state
|
State types to include in tracing. Normally Planned, Designed and In use.
|
Operational mode
Normal

|
Actual
|
With this pre-checked, the network is traced with regard to the position of "Actual connection state".
|
|
|
Stop types
|
Here, the desired feeding point can be defined by tracing method, Enter point in the network. Normally, a suggestion is automatically obtained when marking the voltage level.
Example: If the highest voltage level is 20 kV and the Tracing method "Select object" is checked, a tracing stop suggestion, Rail 20 kV, will be obtained.
Alternative stop types can be entered manually, but it can be difficult to find a unique stop point. If you choose e.g. cable pillar, you get a list of all cable pillars at this voltage level when tracing the network.
Select voltage level and stop type. Then click on "Add".
|
Stop object
|
Set up individual objects where the trace should stop. This method is easier and more straightforward to use than manual stop type selection.
If trace method Select feeding point is selected, stop types that block unwanted mains parts can/should be identified. For example, outgoing groups can be stopped in a station to only count one or a few groups.
Even if a different tracing method has been selected, the search can be limited by adding stop objects. This can be valuable when you want to perform calculations on a smaller part of a large network with the same voltage level, e.g. during extension. Switches are the best objects to choose as stop objects.
1.Click the Add button.
2.Select object in the map.
The object appears in the Select stop object field. Stop objects are temporarily marked in red in the map. The color marking disappears when tracing for network calculation or autoschema is started.
|
Bypass switches
|
The function Bypass switches is used to include in tracing and calculation objects that are temporarily in switching mode "Off" when Normal switching mode is selected as Operating mode. The coupling state of the objects in this list is counted as "On", regardless of their actual coupling state.
1.Click the Add button.
2.Select object in the map.
The object appears in the Bypass switches field. In the map, the object is temporarily marked with green color. The color marking disappears when tracing for network calculation or autoscheme is started.
