The menu Probes & 3-phase appears when the mouse moves over this item in the Component selection menu or when the user hits the P character.
Probes are components for monitoring the node or branch voltage, branch current or TACS values. In the Open Probe dialog you can specify the number of phases to connect to and select phases to be monitored.

Description |
Probe Volt |
PROBE_V |
|
Selecting this item draws the voltage probe to specify a node voltage-to-ground output request in the ATP-file. |
Probe line volt |
PROBE_D |
|
Selecting this item draws the line voltage probe to specify voltage difference output requests in the ATP-file. Useful for 3-phase circuits where the user can specify A-B, B-C, C-A or A-C, B-A, C-B voltages. |
Probe Branch volt |
PROBE_B |
|
Selecting this item draws the branch voltage probe to specify a branch voltage output requests in the ATP-file. |
Probe Curr |
PROBE_I |
|
Selecting this item inserts a current probe (measuring switch) into the circuit to specify current output request in column 80 in the ATP-file. The number of monitored phases are user selectable. Add current node: Two switches in series. Middle node available. |
Probe Tacs |
PROBE_T |
|
Selecting this item draws the Tacs probe to specify signal output and inserts TACS Type-33 object into the ATP-file |
Probe Model |
PROBE_M |
|
Selecting this item draws the Model probe which can be added to Models output nodes. Inserts RECORDS cards into ATP-file. |
Splitter |
SPLITTER |
|
The Splitter object is a transformation between a 3-phase node and three 1-phase nodes. The object has 0 data and 4 nodes. |
Collector |
COLLECTOR |
|
The Collector object is a component with a single multi-phase node. It is useful in Compress, since only components can have external nodes, not connections. |
Transp 1 ABC-BCA |
TRANSP1 |
|
Transposition of 3-phase nodes. Change the phase sequence from ABC to BCA. |
Transp 2 ABC-CAB |
TRANSP2 |
|
Transposition of 3-phase nodes. Change the phase sequence from ABC to CAB. |
Transp 3 ABC-CBA |
TRANSP3 |
|
Transposition of 3-phase nodes. Change the phase sequence from ABC to CBA. |
Transp 4 ABC-ACB |
TRANSP4 |
|
Transposition of 3-phase nodes. Change the phase sequence from ABC to ACB. |
ABC reference |
ABC |
|
When attached to a 3-phase node in the circuit this node becomes the “master” node with phase sequence ABC. The other nodes will adapt this setting. |
DEF reference |
DEF |
|
When attached to a 3-phase node in the circuit this node becomes the “master” node with phase sequence DEF. The other nodes will adapt this setting. A combination of ABC and DEF references is possible for e.g. in 6-phase circuits. |
|
When a splitter is rotated the phase sequence of the single-phase side changes as shown left. |
|
If a name is given to the 3-phase node, the letters A B C are added automatically on the single-phase side of splitters. |
Note! Do not give names to nodes at the single-phase side of splitters and do not connect splitters together on the single-phase side (except all three phases). I.e. next two examples are illegal!
Disconnection is illegal this way! Transposition is illegal this way! This is legal, however.
Handling of transpositions for objects with several 3-phase nodes is controlled by the circuit number Kind under Library | Edit/New USP / Nodes (see in 4.2.6.2). 3-phase nodes having the same Circuit property will receive the same phase sequence.
