What it represents
A power-factor meter indicates the relationship between real and apparent power according to the instrument's measurement method. Its voltage and current inputs need phase-consistent connections.
How to read it
- Identify the instrument's sign convention and whether it reports displacement or total power factor.
- 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
- Show current and voltage inputs
- State measurement convention
- Reference CT and VT ratios
A distinction that matters
Power factor is a ratio; it is not reactive power in kvar.
