What it represents

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.

How to read it

  • State rated kvar at the specified system voltage and frequency.
  • The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.

Information to show or reference

  • Record kvar and voltage
  • Show connection and switching
  • Reference discharge/protection arrangement

A distinction that matters

A power-factor capacitor is a power-circuit assembly, not a generic small-signal filter capacitor.
