Matching functional counterpart linked separately. Independently drawn educational geometry; not a certified IEEE glyph or database identifier. Related representation: [Three-phase power-factor capacitor](https://eloragrid.ai/symbols/three-phase-power-factor-capacitor) IEEE-library form of three-phase power-factor capacitor: a three-phase capacitor assembly provides a documented reactive-power function connected to the power circuit. ## In plain English ### What does ANSI/IEEE Three-phase power-factor capacitor form mean? This reference locates three-phase power-factor capacitor in Autodesk's IEEE-oriented motor control family. A three-phase capacitor assembly provides a documented reactive-power function connected to the power circuit. The schematic needs its connection, switching and protective devices as separate elements. The public library uses HCA113 for its horizontal representation; this is a vendor block name, not an IEEE standards symbol number. ### A simple example Trace each winding, supply and accessible neutral through the complete machine or transformer connection diagram. Keep the phase arrangement, terminal labels and any clock notation attached to the device; neither the convention label nor this educational outline supplies its ratings. ### What the drawings help you do State rated kvar at the specified system voltage and frequency. A power-factor capacitor is a power-circuit assembly, not a generic small-signal filter capacitor. The linked functional counterpart explains the same operating role in its own drawing context; agreement of every detailed convention mark is not asserted. ### This particular reference IEEE-library form of three-phase power-factor capacitor: a three-phase capacitor assembly provides a documented reactive-power function connected to the power circuit. A power-factor capacitor is a power-circuit assembly, not a generic small-signal filter capacitor. ### Terms - Winding: A coil of conductor inside an electrical machine or transformer. - Phase: One of the related AC waveforms in a power system. - Terminal: An identified point where a conductor connects.
