Week 8 Video Lecture – Power Factor
Consider the circuit demonstrated in
this week’s presentation. Analyze the circuit to determine the following
(include both polar and complex forms where applicable):
Real Power (Watts)
Reactive Power (VARs)
Apparent Power (Vas)
Construct the circuit in MultiSIM
and run a Single Frequency Analysis to confirm your calculations for the phasor
values in part 2. Capture a screenshot of the analysis for both
Magnitude/Phase (polar) and Real/Imaginary (complex). Create a table with your
expected and measured results.
Measure the real power of the
circuit and the power factor using a watt meter. Capture a screenshot of the
watt meter readings.
Based upon the power factor,
determine the value of the capacitors needed in each case to bring the power
factor to the following values. Be sure to show your calculations.
. Power Factor = 0.85
Power Factor = 0.95
Power Factor = 1.00
Insert each of the capacitor values
found in step 5 into the circuit one at time and confirm the power factor
correction with a watt meter. Use a 5% tolerance for the capacitors. Capture
a screenshot of the watt meter for each case. Create a table of expected and
measured results. Comment on how well the desired power factor was achieved and
any reasons for discrepancies.
