II. Understanding Reactive Power
A. Definition of Reactive Power
Reactive power is the power that oscillates between the source and the load in an AC (alternating current) system. Unlike active power, which performs useful work (like lighting a bulb or running a motor), reactive power does not contribute to the actual work done but is necessary for maintaining the voltage levels that enable active power to flow.
B. Difference Between Active Power, Reactive Power, and Apparent Power
Active Power (P): Measured in watts (W), this is the actual power consumed by electrical devices to perform work.
Reactive Power (Q): Measured in volt-amperes reactive (VAR), this power is used to maintain the electric and magnetic fields in inductive and capacitive devices.
Apparent Power (S): Measured in volt-amperes (VA), this is the combination of active and reactive power, represented as \( S = \sqrt{P^2 + Q^2} \).
C. The Concept of Power Factor
1. Definition and Importance
The power factor (PF) is the ratio of active power to apparent power, expressed as a decimal or percentage. It indicates how effectively electrical power is being converted into useful work. A power factor of 1 (or 100%) signifies that all the power is being used effectively, while a lower power factor indicates inefficiencies.
