What sizes of capacitors are commonly used in the power industry according to power utilities?

Capacitors play a significant role in power systems, primarily for power factor correction and voltage support. All the specified sizes—5 KVA, 10 KVA, 15 KVA, 25 KVA, 50 KVA, 100 KVA, 150 KVA, and 200 KVA—are indeed commonly used in the industry.

The diversity in sizes allows utilities to select capacitors based on the specific needs of different applications and systems. For instance, smaller capacitors like 5 KVA and 10 KVA are often used in residential or smaller commercial applications, while larger capacitors are suitable for industrial or commercial setups to manage larger power demands and improve efficiency.

By having various sizes available, utilities can customize solutions for different situations, ensuring that power factor correction is optimized across a wide range of facilities and equipment. This flexibility in capacitor sizing is essential for maintaining system stability and reducing energy costs overall.
