It’s Good to have in mind practical aspects: case of a low voltage switchboard To achieve the effective installation of the surge protection, the surge arrester’s connections to the grid should be as short as possible. Any cable crossed by a lightning impulse current has a significant voltage to be added to the Surge Protection Device (SPD) residual voltage.

Reducing power losses by optimizing equipment locations
Do you realize that power losses in a electrical installation could represent up to 7 % of the electrical consumption ?
LV cables and transformers are the most contributors to these operating losses, around 95 % as shown here below
Lightning & Surge protection: Advice to ensure a guaranteed lightning protection for a low voltage electrical installation
I have found a new electrical software on Internet: Simaris Design Basic. It is a software for electrical installation calculation: short-circuit calculations, cables sizing and protection devices choice and settings. This is a new version. I knew the old version of this software – 1.5, which is not available any more.
I find the existing software for the calculation of Electrical Installation difficult and long to use. Sometimes, I need to make a simple calculation or verification and I do not need to create a complete network to do it
Recently I have discovered some small calculators, some of them are too much simplified, but I find the idea good. There is for example… (more…)
