Capacitor (3-phase)

Three-phase capacitor bank — three identical capacitors connected between the line ports and a neutral (Y) or between phases (delta). Used for power-factor correction and harmonic filtering.

Parameters

Config

Name	Label	Type	Default	Units	Description
capacitance	C	double	0.01	—	Per-phase capacitance (F). The 3-phase capacitor is three independent per-phase capacitors 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	—	Observable id for Phase A branch current. Blank skips this phase.
current_name_b	Phase B current name	string	Ib	—	Observable id for Phase B branch current. Blank skips this phase.
current_name_c	Phase C current name	string	Ic	—	Observable id for Phase C branch current. Blank skips this phase.

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).
