The current source always has a parallel impedance. This impedance is made up of series or parallel connected R, L, C elements.
Mask and Parameters
SI or pu units:
- SI: Specifies the values of the RLC elements, voltage, current or frequency in international units (ohm, henry, farad, volt, ampere and hertz);
- pu: Specifies the values of the RLC elements, voltage, current or frequency in pu;
| Name | Description | Unit |

| Starting mode (Slow/Fast) | If “Fast”, the source is immediately activated or deactivated. If “Slow”, when the source is activated, the amplitude of the source increases linearly from zero to the steady-state value. When the source is deactivate, the amplitude of the source decreases linearly from the steady-state value to zero. | - |
| RLC type | Series (series R, L, C) or parallel (parallel R, L, C) | - |
| Base Power (total) | Base power for three phase | MVA |
Base voltage (rmsLN) | Base voltage phase to ground | kV |
| Base Frequency | Base frequency | Hz |
| Amplitude (peak) | Peak value of the amplitude for the source current in amperes (or pu) for each phase | A (or pu) |
| Angle | Angle of phase A in degrees. The current source is always in balanced and positive sequence. | degrees |
