Utility companies react differently to their customers’ power factor. If the overall load is small, some will often ignore it. Others offer incentives to increase power factor. However, the majority of utilities charge customers an additional fee if the power factor is below 0.9. Some require a minimum of 0.95.
Power factor correction capacitors can be installed and controlled in several ways. One is static or fixed correction, and the other is central or bulk correction.
In the next “Pump Ed 101,” I will discuss how capacitors are installed and the impact of their location in the system. I will also provide references that offer detailed information on capacitor selection and installation.
