PBT-Q

The software PBT-Q allows in a simple and quick way to design and estimate the electrical Low voltage installation system.

Main functions offered by the software (this tool):

- drawing of the electrical scheme,

- calculation of the parameters of the electric system,

- automatic or manual configuration of the structure,

- thermic verification,

- auxiliary circuits draw,

- measure circuits draw,

- estimation of the system.

Drawing of the scheme

The modality of the drawing of the single line electrical scheme is semiautomatic type : once chosen the component to be inserted in the scheme and defined the connection (range, parallel, set up of the new board), the symbol is positioned automatically on the drawing sheet. PBT also has an additional graphic drawing modality, that allows to insert texts, lines, shapes with personalized characteristics.

Calculation of the electric system
Concluded with drawing of the single line electrical scheme, the programme does the calculation of the parameters of the electric system and chooses the components:

- load current and short circuit;
- voltage drop;
- dimensioning of the wiring;
- selection of the manoeuvre and protection devices.

The information and the relative data of the installation system (type of distribution system, supply characteristics, etc.) and of the components(length and type of conductor, data of the loads, etc.), can be inserted and/or modified at anytime (before or after the dimensioning). The electric parameters of the devices are put automatically in the diagram, and the single headings can be personalized by the user.
It is possible to even “block” all or only the selected devices and/or wiring: the programme during the check phase, signals possible anomalies (and suggests the replace of the blocked components with more suitable ones).

The presence of the photos of the devices (switches, measuring devices, signalling, commands, etc.) make the selection much easier.

The devices can be accessorized, where available, the execution can also be selected (fixed, plug-in, withdrawable, etc.).
The programme also has a series of functions and short-cuts that make the planning quicker and more efficient (for example the direct selection of the symbols of the message window, operation allows to modify, in an immediate way all the data that the messages refers to).

Configuration of the of the structure
Realized the single line electric scheme and dimensioned the manoeuvre and protection devices, it is possible to configure the structure in automatic or manual way.
Automatic board configuration (new version’s news): by one click, PBT-Q selects a complete board, immediately drawn (and priced), that can be modified by the user; during the modifications, the enclosures is updated in real time (draw and price).
Manual board configuration: the programme offers all the compatible enclosures with the devices present in the circuit and allows in a simple way to realize the board, showing (while making the board) both the shape of the devices to be inserted (highlighting those already inserted), both the structure of the scheme (highlighting also here the components already inserted). To complete the board it is possible to select also the busbar distribution system among those compatible with the enclosures used.
The programme, finally carries out the thermic verification, as prescribed by the electric enclosure standard, according to various methods selected by the user.

Quick estimation
The programme consents in carrying out a quick estimation by selecting all the devices to be inserted thru proper filters (data, description or directly from the code) or by direct importing of material list from other softwares (Word, Excel, Text, etc.).
Auxiliary and measure circuits draw (new version’s news)
By PBT-Q you can draw auxiliary and measure circuits, using a complete symbols library. To realize a diagram, it’s possible whether insert symbols in a free way or use the elements of the devices inserted in the electrical diagram (coils, contacts, instruments, etc.). All the operations are very simple, aided and facilitated from automatisms (automatic symbols denominating, colouring and assembling, easy draw of the connections that accommodate themselves to the symbols movement).

Documentation
The project documentation (schemes, front of the board, installation/board/devices data, conformity declarations, list of materials) is personalizable (for example company’s logo) and exportable in various formats (xls, rtf, pdf, txt, html e dxf).
