Resistor (3-phase)

Three-phase resistor — three identical resistors, one per phase. Common for line-loss representation and balanced damping.

Parameters

Config

Name	Label	Type	Default	Units	Description
`resistance`	R	`double`	`1`	`Ohms` (`Ω`, `kΩ`, `pu`, `S`)	Per-phase resistance. Pick a unit from the dropdown; pu / Siemens conversions read the bases from the Units tab. The 3-phase resistor is three independent per-phase resistors sharing this value, no neutral coupling.
`measure_current`	Measure current	enum (`Off` / `On`)	`0`	—	Emit per-phase branch current as simulator observables.

Current Monitoring

Name	Label	Type	Default	Units	Description
`current_name_a`	Phase A current name	`string`	`Ia`	—	Signal name for Phase A branch current. Blank skips this phase.
`current_name_b`	Phase B current name	`string`	`Ib`	—	Signal name for Phase B branch current. Blank skips this phase.
`current_name_c`	Phase C current name	`string`	`Ic`	—	Signal name for Phase C branch current. Blank skips this phase.

Units

Name	Label	Type	Default	Units	Description
`S_base`	S_base (MVA)	`double`	`100`	—	System base apparent power in MVA. Used by `pu` impedance / admittance conversions in this component's `computations` block.
`V_base`	V_base (kV)	`double`	`230`	—	Base RMS line-to-line voltage in kV. Used by `pu` impedance / admittance conversions in this component's `computations` block.

Observables

Signal	Type	Default name	Enable	Description
`branchCurrent_a`	`signal`	from `current_name_a`	`measure_current`	Phase A branch current (A).
`branchCurrent_b`	`signal`	from `current_name_b`	`measure_current`	Phase B branch current (A).
`branchCurrent_c`	`signal`	from `current_name_c`	`measure_current`	Phase C branch current (A).
