Do capacitors reduce line losses?
Using capacitors to supply reactive power reduces the amount of current in the line. Since line losses are a function of the current squared,I2R, reducing reactive power flow on lines significantly reduces losses. Engineers widely use the “2/3 rule” for sizing and placing capacitors to optimally reduce losses.
What are the benefits of a capacitor?
Also the Capacitors reduce the current flowing through the distribution lines, which directly decreases I2R losses (active power losses). This leads to more efficient energy distribution, and Reducing Active Power Losses. The Capacitors provide reactive power locally, which improves the power factor of the system.
Does capacitor placement reduce voltage deviations from nominal value?
Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines. The optimized capacitor placement minimized the current flow, thereby reducing resistive losses.
How do capacitors affect voltage levels across a distribution network?
The placement of capacitors resulted in improved voltage levels across the distribution network. Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines.
Do capacitors reduce voltage drop?
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.

I would estimate the heating losses in 5 KVAR to 20 KVAR PF correction caps to be a few 10s of watts, not in the kiloWatt range.

We will be very interested in hearing what the payback interval is when caps are used to reduce line current I 2 R losses. Bill-----
