If possible What is the best way to model a Solar connection ?

 I'm sure I have seen a Video on this but I cant recall where is was.

Installation and licence issues / UK forms - which file is client and installation details?

« Last post by Doodley on 04 February 2023, 10:02 »

Hi all,
I've changed computers and need to transfer my saved client and installation details to the new computer. Does anyone know which file this is please? I presume I just need to delete the file on the new computer and replace it with the one from the old?

Thank you

It is not automatic. You will need to drag and drop a suitable symbol from the symbols tab onto the drawing area.

The downside is symbols can only be dropped on conductors. In order to draw an earth electrode symbol attached to a panel is to use "drawing mode on entity" option.

You select the panel you want to draw the symbol and activate the "drawing mode on entity" from the toolbar. From there you can either create your own symbol using CAD tools, or drag and drop one of the symbols from the symbols area. Then deactivate the drawing mode.

Check this link for details.

Hi,
Is it possible to also show the Earth Electrode symbol in the schematic where Local Earthing is selected?

Thanks

Hello,

The socket outlet with RCD component is available now.

You can select BS7288 RCD Protected Socket Outlets option from the RCD/Earth fault protection selection list.

Hello,

We are implementing a function to support this. See this video showing the function that will be available soon: https://nextcloud.com.gr/modecsoft/index.php/s/5JnmRwfgecdeetY

Is there a way to put the RCD on the Socket Outlet(s)/Load and not the DB/Source?

ElectricalOM for Advanced Users / Re: 460 V split phase

« Last post by Mert on 06 June 2022, 10:04 »

Supply component does not have any settings to enable you to model a split phase supply at the moment, unfortunately.

However, you may try to model this situation by inserting a 3ph Y-D supply, set at 230VAC Ph-N. This will set Ph-Ph to 460VAC. Then you can insert a JB, just to act as a connection point, and 2no TX,  which secondary is set to 230, connected to L1-L2 of the JB.

Cable between the supply and the JB will be a three phase cable, and you will be able to see the neutral current but this will not be accurate because ElectricalOM will still try to model a 3ph system. You can remove the conductors and OCPDs of TXes to model the JB & 2no TX as a single node.

The downside is that as you insert actual loads, you will also start loading L1 and L2 conductors of the main supply cable. An unbalanced load warning will be displayed, which can be ignored

ElectricalOM for Advanced Users / 460 V split phase

« Last post by Sidewinder on 04 June 2022, 06:02 »

Hello,
I am having trouble modelling a split phase supply.
This supply is a UK 230 V supply from single phase 11kV.
It is two off 230 V supplies with a common centre tapped N, like the USA 120/240 supply or the 55-0-55 ELV supply for power tools.
It is common in farms and rural areas with only single-phase HV, and more power is required.
Mathematically the N current is the difference between the current in L1 & that in L2, so the N cable size is not an issue, but I can't find that power source to integrate into my EOM model.
It's just not a 3-phase supply as we know it, i.e. 120 deg 230/400 V, nor is it single phase 230 V & N.
You can get up to 200 A (2 x 100 A) of current from the single-phase HV transformer with this system down a single 3 or 4 core cable.
It means you can use domestic consumer units, etc. It is intended for high load domestic premises.
It is common in South Wales as we have a large "area of outstanding natural beauty" not served with 3-phase HV!
I suspect it may be similar in other rural areas.
