 What's included?

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:

  1. 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.)
  2. Distribution boards: (with busbars, without busbar, sub-distribution boards etc.)
  3. Final circuits: (electrical consumers) ranging from general devices, motors (including DOL, soft starter, reverse-duty and frequency converter), power outlets up to special dummy loads. You even have a possibility to insert a charging unit for electric cars. Talking about awesomeness :)

I definitely highly recommend this software to all of you who work in the electrical engineering field. Even if you don't enroll in my course, I recommend that you invest some time to get to know this program. It's worth it.

I've been using Simaris for years now on many different project across industries and it has always served me well.
