electricalpy 0.0.22

computing functions for electrical engineers

# ElectricalPy

Electricalpy is a python module developed to be used by the electrical engineers. It aims to automate the conventional procedures of calculating and plotting of electrical parameters.

Installation

Use command pip install electricalpy to install it in your computer

Major functions

• As of now, this is the only python module that can solve any linear electrical circuit both with dependent and independent sources and in the presence of reactive elements
• Also it is the only python module that could plot the circle diagram of induction motor from the data of Open circuit and Short Circuit tests

Other functions

• Conversion of two port parameters
• RMS and AVG calculation of any waveform
• RH stablity criteria
• Star to Delta conversions
• Rectangular to Polar conversion
• Series and Parallel calculations

electricalpy.solve_circuit(ckt):

This function takes a netlist ( matrix describing the circuit connections ) as input and returns the node voltages as the output.

Rules for describing a circuit or netlist.

Independent Voltage Source

The direction of current through any Voltage source is assumed form positive terminal to negative terminal. The netlist of Independent voltage source is as follows

• [ "V.1", A, B, Vab ]

Delete a file

You can delete the current file by clicking the Remove button in the file explorer. The file will be moved into the Trash folder and automatically deleted after 7 days of inactivity.

Export a file

You can export the current file by clicking Export to disk in the menu. You can choose to export the file as plain Markdown, as HTML using a Handlebars template or as a PDF.

Synchronization

Synchronization is one of the biggest features of StackEdit. It enables you to synchronize any file in your workspace with other files stored in your Google Drive, your Dropbox and your GitHub accounts. This allows you to keep writing on other devices, collaborate with people you share the file with, integrate easily into your workflow... The synchronization mechanism takes place every minute in the background, downloading, merging, and uploading file modifications.

There are two types of synchronization and they can complement each other:

• The workspace synchronization will sync all your files, folders and settings automatically. This will allow you to fetch your workspace on any other device.

  To start syncing your workspace, just sign in with Google in the menu.

• The file synchronization will keep one file of the workspace synced with one or multiple files in Google Drive, Dropbox or GitHub.

  Before starting to sync files, you must link an account in the Synchronize sub-menu.

Open a file

You can open a file from Google Drive, Dropbox or GitHub by opening the Synchronize sub-menu and clicking Open from. Once opened in the workspace, any modification in the file will be automatically synced.

Save a file

You can save any file of the workspace to Google Drive, Dropbox or GitHub by opening the Synchronize sub-menu and clicking Save on. Even if a file in the workspace is already synced, you can save it to another location. StackEdit can sync one file with multiple locations and accounts.

Synchronize a file

Once your file is linked to a synchronized location, StackEdit will periodically synchronize it by downloading/uploading any modification. A merge will be performed if necessary and conflicts will be resolved.

If you just have modified your file and you want to force syncing, click the Synchronize now button in the navigation bar.

Note: The Synchronize now button is disabled if you have no file to synchronize.

Manage file synchronization

Since one file can be synced with multiple locations, you can list and manage synchronized locations by clicking File synchronization in the Synchronize sub-menu. This allows you to list and remove synchronized locations that are linked to your file.

Publication

Publishing in StackEdit makes it simple for you to publish online your files. Once you're happy with a file, you can publish it to different hosting platforms like Blogger, Dropbox, Gist, GitHub, Google Drive, WordPress and Zendesk. With Handlebars templates, you have full control over what you export.

Before starting to publish, you must link an account in the Publish sub-menu.

Publish a File

You can publish your file by opening the Publish sub-menu and by clicking Publish to. For some locations, you can choose between the following formats:

• Markdown: publish the Markdown text on a website that can interpret it (GitHub for instance),
• HTML: publish the file converted to HTML via a Handlebars template (on a blog for example).

Update a publication

After publishing, StackEdit keeps your file linked to that publication which makes it easy for you to re-publish it. Once you have modified your file and you want to update your publication, click on the Publish now button in the navigation bar.

Note: The Publish now button is disabled if your file has not been published yet.

Manage file publication

Since one file can be published to multiple locations, you can list and manage publish locations by clicking File publication in the Publish sub-menu. This allows you to list and remove publication locations that are linked to your file.

Markdown extensions

StackEdit extends the standard Markdown syntax by adding extra Markdown extensions, providing you with some nice features.

ProTip: You can disable any Markdown extension in the File properties dialog.

SmartyPants

SmartyPants converts ASCII punctuation characters into "smart" typographic punctuation HTML entities. For example:

	ASCII	HTML
Single backticks	'Isn't this fun?'	'Isn't this fun?'
Quotes	"Isn't this fun?"	"Isn't this fun?"
Dashes	-- is en-dash, --- is em-dash	-- is en-dash, --- is em-dash

KaTeX

You can render LaTeX mathematical expressions using KaTeX:

The Gamma function satisfying $\Gamma(n) = (n-1)!\quad\forall n\in\mathbb N$ is via the Euler integral

$$ \Gamma(z) = \int_0^\infty t^{z-1}e^{-t}dt,. $$

You can find more information about LaTeX mathematical expressions here.

UML diagrams

You can render UML diagrams using Mermaid. For example, this will produce a sequence diagram:

sequenceDiagram
Alice ->> Bob: Hello Bob, how are you?
Bob-->>John: How about you John?
Bob--x Alice: I am good thanks!
Bob-x John: I am good thanks!
Note right of John: Bob thinks a long<br/>long time, so long<br/>that the text does<br/>not fit on a row.

Bob-->Alice: Checking with John...
Alice->John: Yes... John, how are you?

And this will produce a flow chart:

graph LR
A[Square Rect] -- Link text --> B((Circle))
A --> C(Round Rect)
B --> D{Rhombus}
C --> D
