24 :POWer Commands
:POWer:QUALity:TYPE
(see page 1138)
Command Syntax
:POWer:QUALity:TYPE <quality>
<quality> ::= {FACTor | REAL | APParent | REACtive | CRESt | ANGLe}
The :POWer:QUALity:TYPE command selects the type of measurement to
make in the power quality analysis:
• FACTor — Power Factor — Ratio of the actual power to the apparent
power.
• REAL — Real (Actual) Power — The portion of power flow that, averaged
over a complete cycle of the AC waveform, results in net transfer of
energy in one direction.
• APParent — Apparent Power — The portion of power flow due to stored
energy, which returns to the source in each cycle.
• REACtive — Reactive Power — The difference between apparent power
and real power due to reactance.
• CRESt — Crest Factor — Crest factor is the ratio between the
instantaneous peak current/voltage required by the load and the RMS
current/voltage (RMS stands for Root Mean Square, which is a type of
average).
• ANGLe — Phase Angle — In the power triangle (the right triangle where
apparent_power
2
= real_power
2
+ reactive_power
2
), phase angle is the
angle between the apparent power and the real power, indicating the
amount of reactive power.
Query Syntax
:POWer:QUALity:TYPE?
The :POWer:QUALity:TYPE query returns the selected power quality
measurement type.
