This property sets/gets the resistance in OHMS of the active Winding Neutral  resistor of wye (star)-connected winding. If entered as a negative value, the neutral is assumed to be open, or floating. To solidly ground the neutral, connect the neutral conductor to Node 0 in the Bus property spec for this winding. For example: Bus=MyBusName., which is generally the default connection. Default = -1. This is an illegal values to simply designate that the neutral is floating and connected according to the bus definition. This is the common case for most OpenDSS circuit definitions.
