 | Transformers Properties |
[This is preliminary documentation and is subject to change.]
The Transformers type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | AllLossesByType |
Complex array with the losses by type (total losses, load losses, no-load losses), in VA, concatenated for ALL transformers
|
| AllNames |
Array of strings with all Transformer names in the circuit.
|
| CoreType |
Transformer Core Type: 0=shell;1 = 1-phase; 3= 3-leg; 5= 5-leg
|
| Count |
Number of Transformer objects in active circuit.
|
| First |
Sets the first Transformer active. Returns 0 if no more.
|
| idx |
Get/set active Transformer by index; index is 1-based: 1..count
|
| IsDelta |
Active Winding delta or wye connection?
|
| kV |
Active Winding kV rating. Phase-phase for 2 or 3 phases, actual winding kV for 1 phase transformer.
|
| kVA |
Active Winding kVA rating. On winding 1, this also determines normal and emergency current ratings for all windings.
|
| LossesByType |
Complex array with the losses by type (total losses, load losses, no-load losses), in VA
|
| MaxTap |
Active Winding maximum tap in per-unit.
|
| MinTap |
Active Winding minimum tap in per-unit.
|
| Name |
Sets the active Transformer by Name.
|
| Next |
Sets the next Transformer active. Returns 0 if no more.
|
| NumTaps |
Active Winding number of tap steps betwein MinTap and MaxTap.
|
| NumWindings |
Number of windings on this transformer. Allocates memory; set or change this property first.
|
| R |
Active Winding resistance in %
|
| RdcOhms |
dc Resistance of active winding in ohms for GIC analysis
|
| Rneut |
Active Winding neutral resistance [ohms] for wye connections. Set less than zero for ungrounded wye.
|
| strWdgCurrents |
All winding currents in CSV string form like the WdgCurrents property
|
| Tap |
Active Winding tap in per-unit.
|
| Wdg |
Active Winding Number from 1..NumWindings. Update this before reading or setting a sequence of winding properties (R, Tap, kV, kVA, etc.)
|
| WdgCurrents |
All Winding currents (ph1, wdg1, wdg2,... ph2, wdg1, wdg2 ...)
|
| WdgVoltages |
Complex array of voltages for active winding
|
| XfmrCode |
Name of an XfrmCode that supplies electircal parameters for this Transformer.
|
| Xhl |
Percent reactance between windings 1 and 2, on winding 1 kVA base. Use for 2-winding or 3-winding transformers.
|
| Xht |
Percent reactance between windigns 1 and 3, on winding 1 kVA base. Use for 3-winding transformers only.
|
| Xlt |
Percent reactance between windings 2 and 3, on winding 1 kVA base. Use for 3-winding transformers only.
|
| Xneut |
Active Winding neutral reactance [ohms] for wye connections.
