Our release on August 11, 2021 adds "power factor" to the variables you can graph in the Visualizer for time series data.
Power factor (usually given in a percentage), is the relationship between power consumption that "does work" and "non-working power" (apparent power). Thus, power factor can be informative about energy efficiency changes in a device (if there is a trend or change in power factor over time).
Power factor also varies systematically by load type:
- Resistive loads (e.g., incandescent lighting or a space heater) has voltage and current in phase, and a very high percentage of the power consumed is being used for "active work". Thus, power factor will often be near 100%.
- Inductive loads (e.g., spinning motors) often have very low power factors (close to 0%).
In the current release, you can visualize power factor by adding it to any graph in the Visualizer:
