In Ecodial Advance Calculation, value for this parameter ‘Type of system earthing’ will be propagated from top-to-down basis.
Yes, we can also see this parameter on the “LV switchboard”, as “Undefined”.
Example: Create a simple network with Source, LV switchboard, and protection-conductor. Verify the parameter ‘Type of system earthing’ at the feeder circuit protection-conductor. Its value is same as that defined at “Source circuit”.
(In the attached image, we can see the ‘type of system earthing’ at the HV/LV transformer is TNS and same propagated at feeder circuit, which is connected downstream of the network)
