In this tutorial, I will demonstrate how you can connect an HVI air termination rod to

an elevated ring conductor.

If you plan with the HVI system, you have several options to connect the air termination

rod.

You can either conduct directly from the air termination rod to the earthing system, connect

the air termination rod to a second rod, or connect to an elevated ring conductor.

Let's take a look at the last option and connect the air termination rod to the elevated ring

conductor.

Here below we can see that the class of LPS is set to 3.

We have two different options to place the ring on the roof surface.

Our first option is to select the command, lay round wire on roof and place the wire.

The second option is to place a mesh on the roof.

Therefore, we first delete our ring and then choose the respective command from our toolbar

to place the mesh.

And then we delete the connections in the middle of the roof.

Now we can choose if we want to elevate only one wire or more than one.

Start with selecting this wire, clicking right and selecting change support.

Then we select from the drop-down the option to elevate the wire to 675 mm.

To elevate multiple wires at once, we simply need to keep the control button pressed, select

the wires and then we repeat the prior steps.

Now we also elevated the rest of the wires and the connection clamps have been set again.

As a next step, we place an HVI light air termination rod on the roof by choosing the

article from our DIN library.

Once we select the air termination rod, we can choose different options to connect the

rod by clicking right, selecting add down conductor to ring and HVI light.

The program chooses the shortest way to connect the rod to the ring.

Alternatively, we can choose add down conductor to point and define the connection point for

ourselves.

To create a down conductor from the ring, we need an earthing system.

If we do have an existing earthing system, we can choose this command to create a down

conductor from the wire.

In our case, we select the down conductor with HVI light, choose the connection point

and the program does the rest for us.

It is also possible to combine the different variants on the roof.

To do that, we simply choose an HVI long air termination rod from the library, place it

on the roof, select it, click right and connect it with an HVI long conductor to the ring

as well.

As a last step, let's take a look on how to do the connection with an individual approach.

First of all, we open the drop-down menu for the icon lay round wire on roof and choose

the HVI long variant.

The program recognizes automatically that we can only connect this wire to the HVI long

air termination rod.

It cannot be connected to the HVI light air termination rod.

We select the air termination rod and then continue by individually placing the wire

and connecting it to the ring.

Escape terminates the active command and the appropriate connection is made.

It's important to mention that the supports for the variable cable sealing ends are only

done once the separation distance has been calculated.

For the calculation, the maximum length is assumed.

Once the calculation has been done, the exact values are known and the suitable support

can be placed.

Prior to calculating the separation distance, we will create two down conductors, this time

with the HVI long variant.

The separation distance is calculated with the icon in the toolbar.

We can see that the holders are placed but are not yet adapted in the working view.

We click right and switch to realistic view and can now see the appropriate graphic representation

of the holders.

That's it for this tutorial.

Thanks for watching.
