19.3.1.1 Power quality results
The results of " Power Quality"
measurements are provided in two ways:
●
The diagram shows the graphical presentation of:
– the voltage waveform
– the current waveform
– the power waveform that is the product of the current and voltage waveforms
●
The result box displays the numeric measurement results.
To measure and display the power quality, the instrument uses the following measure-
ments and waveforms:
●
"MG 6" to measure the voltage
●
"MG 7"
to measure the current
●
"MG 8" to measure the power
●
"M2" "Math 2" to calculate the power
The used resources are listed in the "Details" tab. See also: Chapter 19.2.3, "Details
tab", on page 1135.
Voltage and current results
The voltage and current results are defined as follows:
Result Description
RMS Square root of the mean of the square of the current
or voltage averaged over N cycles
Peak Highest measured magnitude value of the voltage or
current
Crest factor Peak value / RMS value
Frequency Frequency of the signal
Power results
The power in a system is described by several physical quantities: real power, reactive
power
, complex power, and phase angle. In Figure 19-1, you can see how these quan-
tities are related if the voltage and the current are sinusoidal signals.
