Information

Bestand | Prepare | Information gives an overview of the size of the current network.

Characteristics

Some properties of the network can be saved with the network file with Bestand | Prepare | Characteristics.

General

General characteristics are: customer, city, region, country, project, description, version, state, by and date.

Invisible specifics

A list of the detailed characteristics of object that are not shown in views and reports. It is possible to fill in the characteristics manually or to select the characteristics from the list of characteristics which have already been applied.

History

A very short description of what has been changed in the network on which date and by whom. Moreover a check box can be selected that will make Vision automatically asks for updating the history when saving the network.

Users

A list of users who are authorized to save the network file. The user names are the Windows user names.

Comment

Bestand | Prepare | Comment offers the possibility to store necessary background information of a network as text.

A text field is available for this purpose. If in Options at Editor, General the option 'Show comment after opening' is checked, each time the network file is opened, the comment will be shown on screen. The comment can also be printed.

Hyperlinks

Bestand | Prepare | Hyperlinks offers the possibility to include a number of references to documents, spreadsheets, images or web addresses in a network file. These references have been implemented as hyperlinks.

In the form a new hyperlink can be inserted by placing the cursor in the text field or in the last already defined field and pressing the cursor key 'down' once. A new line will appear, where the characteristics and location to which the hyperlink should point can be entered.

By clicking on a hyperlink with the right mouse button a drop-down menu appears. With 'Browse' explorer is started and a file can be selected. With 'Go to' the corresponding program is started to show the information the hyperlink points to.

Characteristic is a description of the link in text.

Location is the reference to a file or a web address.

Examples:

'C:\My documents\documentation.docx',

'C:\My images\substation.png',

'www.phasetophase.nl'.

Variables

Bestand | Prepare | Variables offers the possibility to define network variables with a name and a value.

These variables can be used by means of their name between percentages in:

•the value of a specific attribute of an object

•the file name of a measurement file of a measurement field

Check

Checking the network for abnormal values is done with Bestand | Prepare | Check.

Abnormal values which do not lead to errors when performing calculations generate a warning or an information notification.

Information notifications are generated by:

•Multiple islanded nodes

•Element with a current> 1000 A

•Cable with an ampacity> 1500 A

•Cable with a length <10 m

•Parallel cables with different lengths

•Connection as modelled as link

•Switch with load capacity> 1500 A

Warnings are generated by:

•Node with simultaneity <0.1

•Node with simultaneity> 1

•Many islanded nodes

•Power supply without short-circuit power

•Element without rated power

•Element with bad cosinus phi

•Transformer load with many small consumers

•Transformer load with a power > 2*transformer rated power

•Cable with a length > 4 times the straight line distance

•Cable part with a small nominal voltage

•Cable section with a resistance <0.01 Ohm / km

•Cable section with a resistance> 10 Ohm / km

•Cable section with a reactance> 1 Ohm / km

•Cable with an amapacity <10 A

•Cable with geographic coordinates which are not continuous

•Cable with a different geographical length

•Branch with no or incorrect zero sequence impedance

•Meshtransformer

•Load switch type different from the rail type

•Power switch type different from the rail type

•Switch or protection in element with low load capacity

•Protection with a trip current> 1.5 * cable load

•Differential protection with less than two measurement points

•Protection without setting

•Duplicate IDs

•Unknown field

•Field connected more often

Error messages are generated by:

•Cable with length < straight line distance

•Inconsistent clock numbers

By double-clicking on a line in the list of error messages with the left mouse button, the object is selected shown in the network diagram.

Once checked and approved, the checking messages can be suppressed per object and per message, by including a line in the specific tab with the 'checked' attribute.

The following texts can be used as values: simultaneity, current, power, cos, consumers, length, geo, main conductor, earth screen, auxiliary, resistance, load capacity, parallel, mesh, protection, type, ID and field.
