Magtrol Model 6530 Three-Phase Power Analyzer
Chapter 3 – Installation/Configuration
SETUP
1-Phase, 2-Wire
•
Measures single-phase power.
•
Can be wired on any input module.
•
The Power Factor is derived from the following equations:
Amps
Σ
= A
x
, Volts
Σ
= V

Active Power = W
Ø
Apparent Power = V

(Where Ø is the phase of operation)
•
Most commonly used for single phase AC and DC motor applications.
The following diagrams show the connections for a 1-Phase, 2-Wire measurement. Only one phase
has been shown for clarity, but any of the three phases may be used.
