Power-factor meter
A power-factor meter indicates the relationship between real and apparent power according to the instrument's measurement method.

What it represents
The power-factor meter form indicates a relationship derived from documented voltage and current inputs. Phase association and sign convention affect interpretation, while total versus displacement power factor depends on the instrument's method.
This is a convention-specific lookup based on the publisher's IEEE-labelled preview. The geometry here is independently drawn to explain the connection or operation; it is not a certified reproduction of the standard graphic.
How to read it
- Check the reported power-factor convention before comparing indications.
- Read the selected library and the project legend together. A vendor block identifier is meaningful within its named library and is not a universal standard-symbol code.
Information to show or reference
- Show voltage/current phases
- State measurement convention
- Reference CT/VT scaling
A distinction that matters
Power factor is a ratio, not reactive power measured in var.
