Electrical Design Bootcamp - LV Power Calculations

*** UPDATES *** - September 23, 2019 - Captions in English (EDITED, not auto-generated). Dear Student,I welcome you to my tutorial about low voltage power calculations using Simaris Design and Simaris Curves from Siemens. Planning of an automation project and the electrical wiring on that project starts with power calculations.

This is one of the first steps I take when I start to work on a new automation system - I plan and dimension my low voltage power system. I've tried years ago different software from all the biggest manufacturers and concluded that Simaris Design is, according to my experience, by far the best one out there to quickly setup a project, create single line diagrams and output all the possible documents that one needs when performing power calculations (project documentation, different list in Excel, e. g.

busbar, cable, device settings, selectivity documentation etc. , single line diagrams in PDF and i DWG/DXF). Language support is great, meaning that you can set your workspace and the single line diagram to the language of your choice.

The same goes for the output documentation. When creating single line diagrams in Simaris Design the devices you use are grouped into three categories:· System infeed: (transformer with primary and secondary side, transformer only with secondary side, coupling to use when you have also emergency power supply, like a diesel aggregate (generator) etc. )· Distribution boards: (with busbars, without busbar, sub-distribution boards etc.
