In this tutorial, I'll show you how you can plan a lightning protection system by

using the HVI long product family.

To do that, I already prepared a 3D building model, including an earthing system, and entered

some relevant project information such as the lightning protection class number 2.

To start our planning process, we choose our preferred material from the DIN library.

The selected lightning rod can now be placed on the desired position on the roof via a

simple click.

In our lightning protection options on the right or in the toolbar, I can activate the

area of protection.

Now I can directly see how placing an additional lightning rod influences the area of protection

and if the building lies within the protected area.

I can save time by pressing the spacebar and repeating the prior active command.

This way I can easily place additional lightning protection rods on the roof.

As an alternative to placing the rods with a mouse click, I can place them by entering

the coordinates.

We can see that the building is not yet protected completely and that we need to adapt some

lightning rods.

For a fast and easy selection, I can set a filter by selecting the lightning rod, clicking

right, choosing filter similar elements and then checking type.

Now I can only select lightning rods and don't accidentally select other parts.

Now I select the two lightning rods up front and replace them with higher rods by changing

the article number in the properties window on the left.

The area of protection automatically adapts with each change.

Since this is not sufficient, I move the other lightning rods until our building is completely

protected and all warning signs disappear.

In the next step, I add the down conductors and hide the area of protection to better

see the results.

I select the lightning rod, click right and choose add down conductor cable.

The program does the rest for me and automatically sets the down conductor and makes the relevant

connections.

I repeat this step for the other lightning rods as well.

Lastly, I check the separation distance and activate the calculation with this icon.

In our case, I see several error messages.

If I click on the message, I see under remarks that the separation distance is too large

due to the high length of the down conductor cable.

If I want to know more about the values, I can activate the separation distance at nodes

and see the values directly at our lightning protection rods.

The high values can be reduced by connecting two lightning protection rods with each other

by pressing the command button, clicking right and selecting add interconnection.

Alternatively, I can add another down conductor.

If we now calculate the separation distance again, we see that the problem has been solved

and the separation distance is compliant.

Again, we can check the values.

That's it for this tutorial.

In separate tutorials, I demonstrate different planning methods.
