Floating Reference
Reference point for measuring the voltage of other components in an ungrounded circuit.

Description
The unit Floating Reference provides an electrical reference point that can be used to measure the voltage of other nodes in an ungrounded electrical circuit.
Unlike the Electrical Reference block, which provides a connection to ground, this block uses capacitance to block DC current.
For details on the operating modes of a three-phase system connected in a * delta* pattern, refer to Problem solving for delta connection of transformer windings.
Parameters
Capacitance - DC blocking capacitance
1 µF (by default) | positive scalar
The physical capacitance between an ungrounded circuit and ground. This capacitance blocks DC current.
Parasitic parallel conductance - Parasitic parallel conductance
`0 1/ohm (by default).
Presents small parasitic effects.
A non-zero value is required for modelling some circuit topologies.
