11.2.2.2 Power quality
In an electric circuit power is a measure for the rate of flow of energy at a certain point
of the circuit. The active power of a circuit, or the energy that can be used for work, is
the portion of energy that is transferred in one direction over a complete cycle of the
AC waveform. In AC circuits, however, inductive and capacitive elements can store
energy temporarily. This portion of the power flow known as reactive power is then
returned to the source without doing any work.
The power quality analysis measurements include the active power, the reactive
power, the apparent power and the power factor. The crest factors and the phase angle
between the current and voltage are also measured. These properties describe the
power transfer in the system and allow you to characterize the power quality of the sys-
tem.
Required probes:
●
Differential voltage probe
●
Current probe
Configuring power quality
For details of the configuration settings, see "Power quality settings" on page 251.
1. Add a new power quality measurement as described in "To add a new power mea-
surement" on page 246.
2. In the "Analysis" tab, tap the "Quality" measurement.
The "Quality" setup dialog opens.
