Types of Electrical Loads and The Power Type They Consume The reactive component (KVAR) of any electrical distribution system can easily be reduced in order to improve power factor by using capacitors. Capacitors are basically reactive loads. They tend to generate reactive power hence they find good use in power factor correction application.
By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load. Reduced current also significantly lowers the I 2 R line losses. Capacitors provide a voltage boost, which cancels part of the drop caused by system loads.
Most noticeably, capacitors reduce losses, free up capacity, and reduce voltage drop. Let’s go a little bit into details. By canceling the reactive power to motors and other loads with low power factor, capacitors decrease the line current. Reduced current frees up capacity; the same circuit can serve more load.
Now, capacitors are used to help generate this reactive power, (as they dissipate power when the inductor consumes it) and are hence placed near the load to reduce the reactive power that needs to be transmitted. I have the following questions: Is my thought process correct? Am I right in my understanding of reactive power?
Capacitors provide power just when reactive loads need it. Just when a motor with low power factor needs power from the system, the capacitor is there to provide it. Then in the next half cycle, the motor releases its excess energy, and the capacitor is there to absorb it. Capacitors and reactive loads exchange this reactive power back and forth.
When capacitors are used to improve power factor , the following benefits will accrue: 1. Reduced electrical power bills 2. Reduces I2R losses in electrical conductors 3. Reduces loading on transformers by releasing system capacity 4. Improves voltage on the electrical distribution system thereby allowing motors to run more efficiently and cooler.
