Neutral (Power System Blockset)

Implement a local common node in the circuit

Library

Description

The Neutral block implements a local common node with a specific node number. If the node number is set to zero, the Neutral block automatically makes a connection to ground. The node number is displayed on the icon. You can use this block to create a floating neutral or to interconnect two points without drawing a connection line.

For the drawing facility, two types of neutral blocks are available in the library: one block with an input and one block with an output.

Example

The following circuit uses three Neutral blocks. Three resistors are connected to a floating neutral (node 50). The phase-to-ground voltage is measured with the u2 block and the phase-to-neutral voltage is measured with the u1 block. This example is available in the psbneutral.mdl file.
