Rneut
(read/write)
This property sets/gets the neutral resistance if the active load is wye-connected. Default = 1. Used to designate high priority loads such as hospitals, etc. Is multiplied by number of customers and load kW during reliability calculations. If entered as a negative value, the neutral can be open, or floating, or it can be connected to node 0 (ground), which is the usual default. If >=0 be sure to explicitly specify the node connection for the neutral, or last, conductor. Otherwise, the neutral impedance will be shorted to ground.
Example
% Create DSS object
DSSObject = actxserver('OpenDSSEngine.DSS')
if ~DSSObject.Start(0),
disp('Unable to start openDSS');
return
end;
DSSText = DSSObject.Text;
DSSCircuit = DSSObject.ActiveCircuit;
% Compile a model
DSSText.Command = 'Compile C:\myPath\myModel.dss';
DSSLoads = DSSCircuit.Loads;
% activates the first load on the list
i = DSSLoads.First;
% gets the neutral resistance for the active load
myRN = DSSLoads.Rneut;
