The Device Tree
The device tree is on the left hand panel
The Device Tree panel
The device tree provides an alternative way of viewing the network to the geo-spatial map.
The device tree provides a representation of the network as a tree view of nodes (transformers, switches, supply points and customers), with each node forming a branch, below which assets energised by that node are displayed. This tree view of the network is only available on distribution network HV feeders, which are normally operated as radial network, with one primary supply point - typically the circuit breaker in the zone substation at the start of the feeder. It is not available for the EHV (or sub-transmission network) which is typically operated at a meshed network.
The device tree can be useful in situations where there is very dense network, such as in urban or CBD areas, and it is difficult to visualise the connectivity and connected customers in the geo-spatial map view.
Opening the device tree
The device tree can be opened by
- pressing the device tree icon on the bottom left of the map,
- from the asset pop up menu on the map, or
- from a supply point from an icon in each row of the customer list.
This is illustrated in the screen shot below.
If the device tree panel is opened from the icon shown on the map, you will need to select the feeder you wish to load into the device tree. This is done with an incremental search drop down, as illustrated in the screen shot below. Each organisation has different conventions for how feeders are named - the feeders available for selection should match the conventions in your organistation.
The device tree will open on the left hand panel. The screen shot below shows the device tree open for HV Feeder BAN001.
Navigating the Device Tree
The device tree behaves in the same way as a set of folders and files in a file system user interface. If there are other devices below a device in the tree, there will be a "plus" 
icon next to the left of the device, and clicking this will expand the tree. That branch of the tree may be collapsed by clicking the "minus" 
icon.
Navigation from the device in the tree to the map is achieved by pressing this icon: 
The 
icon brings up an additional menu against the associated device. The total set of options available are described below, noting that some of these are dependent on the type of device selected and any previous actions performed.
