Electricity User Manual
Chapter 1Introducing the MunsysQ Electricity User Manual
MunsysQ Electricity is used to capture and maintain electricity ring and radial networks in QGIS: substations, transformers, poles, junctions and street lights, the overhead and underground cables between them, and the service connections to the parcels. It does not require GIS expertise: the Electricity menus guide you through each function, and the electricity business rules are applied as you work.
MunsysQ Electricity is one of the MunsysQ applications, alongside MunsysQ Cadastral, Drainage, Roads, Sewer and Water. All of them work on the same Munsys database as Munsys on AutoCAD.
About this manual
This manual describes the functions of MunsysQ Electricity: how an electricity network is captured, checked, posted to the database and maintained. It assumes that you are familiar with:
- the electricity business rules of your organisation
- the MunsysQ panel, QAD command line and edit cycle, as described in the MunsysQ Concepts User Manual
- common GIS terminology.

Chapter 2Getting acquainted with MunsysQ Electricity
About MunsysQ Electricity
An electricity network is built as a ring or radial network from nodes, cables and service connections. It consists of smaller networks for extra high voltage, high voltage, low voltage, street lights and service connections. The connectivity rules of each network are built into the capture functions, so that a cable can only connect nodes that belong to its network: an overhead EHV cable, for example, runs between pylons, and a service connection starts at a transformer, pole, junction or distribution box.
Descriptive information such as cable size and material, cable status and service phase is taken from lookup lists in the database, so that the values are consistent. The electricity business rules are checked before the data is posted to the database.
About electricity objects
Nodes
Nodes show where cables start, end or connect. Each node belongs to one or more node groups, extra high voltage, high voltage, low voltage, street light and service connection, which say which networks it is part of. A switch station, for example, belongs to the EHV and HV groups.
| Node | Meaning |
|---|---|
| Switch Station | The main node where the HV network starts. |
| Standard Sub, Mini Sub, Transformer | Nodes where the LV network starts. |
| Pylon | Distributes overhead EHV. Pylons along a cable are usually intermediate nodes. |
| Air Link | Connects HV cables on overhead lines. |
| Kiosk | Connects HV cables to underground cables. |
| HV Switch | Connects HV cables on overhead or underground cables. |
| Distribution Box | Connects service connections and street lights. |
| Pole | Distributes overhead HV, LV, SL and service cables. Poles along a cable are usually intermediate nodes. |
| HV Junction, LV Junction, SL Junction | Connect several cables of the same network. |
| SL Pole, SL Highmast, Street Light, Billboard | Street light network nodes, used with street light cables. |
The node types available at your site are defined in the database and may differ.
Cables and service connections
Cables are overhead (OH) or underground (UG), in five networks: EHV, HV, LV, SL and SC. Overhead cables run from node to node through intermediate nodes such as poles. Underground cables follow the road reserves, usually at an offset from the parcel boundaries. The length of a cable includes the slack at each node it connects to.
Service connections connect the network to the parcels. They start at a node and end inside the parcel, overhead or underground.
Other electricity objects
- Ducts carry cables under roads.
- Electricity zones are polygons, usually the supply area of a transformer or substation.
- Notes and dimension arrows add information to plans.
Loading MunsysQ Electricity
Before you start, QGIS must be connected to the Munsys data and the MunsysQ panel must show its menus. Connecting is described in Chapter 3 of the MunsysQ Concepts User Manual.
- Open the QGIS project that contains the electricity layers.
- On the MunsysQ panel, select in the list. The Electricity menus are displayed in the menu tree.
The MunsysQ Electricity menus
The Electricity functions are grouped in three menus. The Object and Tools menus below them are shared by all applications and are described in the Concepts User Manual.
| Menu | Contains |
|---|---|
| Electricity settings; placing and inserting nodes; overhead, offset underground and freehand underground cables; overhead and underground service connections; cable direction; electricity zones; notes and dimension arrows; data integrity; posting to the database. | |
| Editing attributes; moving and rotating nodes; changing node, cable and service connection attributes; comments; deleting, undeleting and restoring objects. | |
| Converting blocks, text and polygons to electricity objects. |
The functions used most often are also on toolbars, as in Munsys on AutoCAD. See The Electricity toolbars.
The Electricity toolbars
When Electricity is selected in the list, MunsysQ shows the Electricity toolbars. They have the same buttons as the Electricity toolbars of Munsys on AutoCAD, and each button runs the menu function listed next to it below. The toolbars of the other applications are hidden while Electricity is selected.
- The Integrity toolbar is in the MunsysQ panel, below the list.
- The other toolbars are in the QGIS window, named MunsysQ EMS - Capture and so on. Switch them on or off with . MunsysQ remembers where you place them, also after QGIS is restarted.

The electricity layers
Each type of electricity object is stored in its own spatial table and shown in QGIS as its own layer. A MunsysQ project normally holds them in an Electricity group in the Layers panel.
| Layer | Spatial table | Geometry | Contains |
|---|---|---|---|
| Electricity Nodes | SP_ELNODE | Point | All node types. |
| Electricity Cables | SP_ELCABLE | Line | Overhead and underground cables of all networks. |
| Electricity SCs | SP_ELSERV | Line | Service connections. |
| Electricity Ducts | SP_ELDUCT | Line | Ducts. |
| Electricity Zones | SP_ELZONE | Polygon | Electricity zones and their tags. |
| Electricity Notes | SP_ELNOTE | Point | Notes. |
| Electricity Dimensions, Electricity Dimension Notes | SP_ELDIM, SP_ELNOTE | Point | Dimension arrows and their text. |
MunsysQ finds the layer that a function needs by its spatial table, so you can rename the layers or move them to other groups.
Chapter 3Electricity data in the project
In Munsys on AutoCAD, electricity data is brought into the drawing with the Query menu: all electricity objects, the objects of one network (EHV, HV, LV, SL or SC), the network objects, or zones, ducts, notes and dimensions. In MunsysQ there is no query step. The electricity layers are connected to the database while the project is open, and QGIS reads the objects for the area that you are looking at.
The electricity network
The network is made up of the node, cable and service connection layers, with the notes and dimensions that belong to them. Keep these layers switched on while you capture or change the network, so that every function can find the objects that it connects to.
Working with one network
To see only one network, for example the low voltage network, filter the Electricity Cables layer on its cable type column, or use rule-based styling on that column. Filtering layers is covered in a separate chapter.
Chapter 4Creating electricity data
Capturing electricity data
An electricity network is normally captured in this order:
- Nodes first: substations, transformers, poles, junctions and street lights.
- Cables between the nodes. A cable can only connect nodes of its own network.
- Service connections from the nodes to the parcels.
- Zones, notes and dimension arrows at any time.
When the network is complete, check its integrity and post it to the database.
Electricity capture settings
The Electricity settings are the defaults that the capture and integrity functions use. They are maintained by the GIS administrator in the Munsys Management Console (MMC). You can change many of them for your current session to speed up capture; settings that only the administrator may change are greyed out.
| Group | Settings |
|---|---|
| Cable | Cable Default Offset Distance and Cable material for new cables; Cable Info, which shows the Cable Information dialog box when a cable is captured; the tie-in distance of each node type, the distance from the node at which a cable connects. |
| Node | Align Nodes with Cadastral, Automatic Node Placement, Snap nodes and Node Descriptions, which control how a node is placed; the cable slack and symbol offset distance of each node type; Node Default Offset Distance and Electricity Symbol Scale. |
| Service Connection | Service Connection Length; Service Connection Info, which shows the service connection information dialog box when a service connection is captured; Electricity SC Link Mun ID, the type of object that service connections link to. |
| Electricity Node | Electricity Node Function for new nodes. |
| Duct | Cable Duct Trim or Extend. |
| Integrity | Electricity Cable, Node, SC and Search Tolerance. |
| Dimension, Note, Electricity Zone | Dimension Note Height, Note Tag Height and Zone Tag Height. |
To specify electricity capture settings
- Choose . The Electricity Settings dialog box shows the current session settings.
- Select a setting to see its description in the box below the list.
- To change a value, click it, and then type a new value or choose one from the list.
- Click .
The new values apply to objects that you capture from now on, until you change them again or close QGIS. They do not change objects that already exist.
Capturing electricity nodes
A node is placed next to a parcel boundary or other segment, or inserted on an existing cable, which breaks the cable there. The same node types are on both menus.
Placing nodes
- Choose and the node type, for example .
- At
Select segment to snap to:, select the boundary segment that the node belongs to. - At
Specify insertion point:, click where the node must go. - At
Specify side for node:, click on the side of the segment where the node must lie. - If the Node Descriptions setting is on, select the description of the node from the list and click .
The settings Align Nodes with Cadastral, Snap nodes and the symbol offset distance of the node type control where exactly the node is placed. With Automatic Node Placement on, you are not asked for an insertion point.
Inserting nodes into an existing network
Use this to add a node to a cable that is already captured, without capturing the cable again.
- Choose and the node type.
- Select the point on the cable where the node must go. The cable is broken at that point and the node is placed there.
Capturing cables
Every cable runs from a start node to an end node of its own network. If a node does not allow the cable type, MunsysQ tells you so, for example The selected start node has no substation connectivity for this cable type. The cable is connected to the nodes at the tie-in distance of each node type, and its length includes the cable slack of the nodes.
The Cable Information dialog box
When the Cable Info setting is on, the Cable Information dialog box is shown after you have placed a cable:
- In the group, select the and .
- Set the and of the cable to , or .
Click to apply the values. When the setting is off, the cable receives the defaults.

Select second segment for dimension:, select the point on the second segment that the arrows must align to. - At
Enter distance or [Actual]:, type the distance, press Enter for the Cable Default Offset Distance, or typeAto use the measured distance.
Checking electricity integrity
The integrity check validates new and changed objects against the electricity business rules before they are posted. The rules are held in the database; MunsysQ reads them through the Munsys REST service and applies them, so they are the same as in Munsys on AutoCAD. The check works on the objects that you select, or on all objects with pending edits when nothing is selected. It has two parts:
- Object integrity checks each object on its own: its geometry and its attributes.
- Network integrity checks how the nodes, cables and service connections fit together: that cables end at nodes of their own network, that nodes are connected to the right kinds of cable, and that there are no duplicate cables or nodes. It also looks at neighbouring objects that you did not change.
The checks and the integrity markers are described in full in the Concepts User Manual.
To check electricity object integrity
- Select the electricity objects to check, or select nothing to check all objects with pending edits.
- Choose , or click the button on the Integrity toolbar.
- The MunsysQ Integrity message reports how many objects were checked and failed, how many issues were found, and how many integrity markers were written.
To check electricity network integrity
- Select the part of the network to check, or select nothing to check the objects with pending edits.
- Choose .
- Read the result in the MunsysQ Integrity message.
Browsing integrity markers
Each problem is marked on the map by a point in the Integrity Errors layer. zooms to the markers and opens their attribute table. Select a row and use to go to it.
Erasing integrity markers
asks for confirmation and then removes all the markers. Markers are never posted.
Posting electricity data to the database
- Choose . The Post to Database dialog box lists each electricity layer with pending edits and the number of objects to be inserted, updated and deleted.
- Check the totals and click .
- The Post to Database Results dialog box shows what was posted, with a status and a message for each layer. Click .
After posting, the edit highlight is cleared, your locks on the posted objects are released, and the changes are visible to all users. Connectivity between nodes and cables is updated in the database when you post.
Chapter 5Maintaining electricity data
