Power Factor: What it is and How to Calculate it | Fluke
What is power factor and why is it important? Learn how to calculate the power factor formula, each component of the equation, and why it matters.
How to Improve Power Factor | Fluke
To calculate power factor, divide working power (kW) by apparent power (kVA). While 100% efficiency may not be realistic, there are a few things that impact how power factor is improved.
How to Calculate Fill Factor | Fluke
Fill factor is a way to compare the maximum power of a module (Imp X Vmp = Pmax) to short circuit current (Isc) and open circuit voltage (Voc). It tells us how square a module's I-V curve …
Power Quality Testing Resources & Solutions | Fluke
It displays waveforms and harmonics, performs power measurements for power-factor evaluations, measures inrush current, and logs data over time for later analysis.
How to Size Motors for Load, Horsepower, Motor Horsepower
Power factor is the ratio of true power (kW) to apparent power (kVA). In the absence of power factor measurement tools, a rule of thumb is to estimate power factor at 0.85
How to Analyze I-V Curves | Fluke
A normal I-V curve shape and a performance factor between 90% and 100% usually indicate the correct functioning of the PV source circuit or module. Identifying I-V Curve Deviations Several …
30 day load studies with the Fluke 1735 Power Logger
Use Power Log to graph this data, find the maximum current or power on each phase, compare the three phases and report the largest number. Power Log has a built-in report generator that …
What is unbalanced voltage and current unbalance? | Fluke
If no transients are found in an initial measurement, it is a good practice to measure and log the power quality over time with an advanced industrial power quality logger.
I-V Curve Testing for PV Systems | Fluke
We use the performance factor (PF) in this context to quantify how well a measured I-V curve agrees with a predicted curve. It is reported as a percentage and calculated using the …
How to use a phasor diagram? | Fluke
Learn how to use the phasor diagram on your Fluke power quality tool. Common problems stem from a connection error due to incorrect voltage connection or reversed current connections.
