Description
Block Floating Reference It is an electrical reference point that can be used to measure the voltage of other nodes in an ungrounded electrical circuit.
Unlike the block Electrical Reference which provides a ground connection, this unit uses a capacitance to block the direct current.
For more information about the operating modes of a three-phase system connected according to the Triangle scheme, see Recommendations for delta connection of transformer windings.
Variables
Use the parameter group Initial Targets to set the priority and initial target values for the block parameter variables before modeling. For more information, see Configuring physical blocks using target values.
