Lesson 2: Power Correction Flashcards
1
Q
Power factor is defined as the ? of theta, and it can be calculated by dividing the ? in the power triangle by the ?
A
Cosine of Angle Theta, Divide KW by KVA in the Power Triangle
2
Q
How is Power Factor corrected?
A
Adding a Capacitor in Parallel with the load
3
Q
How to find I (Current) in 3 Phase motor circuit
A
I = W/V*1.73
4
Q
How to find VA in 3 Phase circuit
A
VA = EI1.73
5
Q
How to find TP in 3 Phase circuit with an 80% PF
A
TP = EI1.73*.8

Q
If the goal for power correction is reducing utility bills where should a capacitor be installed?
A
At the main service to achieve a lower price installation
7
Q
Where is the maximum benefit of capacitors felt?
A
When capacitors are placed at the load
