https://brickschema.org/schema/Brick#Power_Factor_Sensor
Sensors measuring power Factor, under periodic conditions, is the ratio of the absolute value of the active power (P) to the apparent power (S).
Focus nodes of this shape (brick:Power_Factor_Sensor) can have the following properties:
| PROPERTY | DESCRIPTION | MIN | MAX | VALUE TYPE | OTHER CONSTRAINTS |
|---|---|---|---|---|---|
| brick:lastKnownValue | last known value The last known value of the Point entity |
0 | 1 | rec:DoubleValueObservation sh:IRI |
