Many facilities have mandates to save energy. Improving energy efficiency offers huge advantages to businesses—reducing the costs of energy and operations— and increasing sustainability. Ⅰ. Abstract Through proven methods including variable frequency drives (VFD), LED lighting and conservation methods and control, many new and existing facilities achieve the savings that they expect. However, many...

Upgrading Older Capacitor Banks is Important As an inexpensive source of reactive power, capacitor banks bring many benefits to a facility.  They are widely deployed to avoid penalties on utility bills, lower distribution losses, increase transformer/Genset capacity, maintain nominal voltage, and to reduce energy losses resulting in decreased carbon emissions. When coupled with reactors, capa...

Power factor penalty in power bills We've found that many people struggle to understand how Power Factor (PF) impacts demand charges. Frequently, end use customers pay a significant premium each month in demand charges because their PF is below a threshold set by the utility in the rate tariff. Oftentimes its not obvious to the untrained eye when there are extra charges associated with a bad PF on...

ZDDQ, a professional manufacturer of power factor correction and harmonic mitigation field since 2001. Today let's talk about power factor correction and energy saving. Power factor correction (PFC) is a technique used to improve the power factor of electrical systems. The power factor is a measure of how effectively the current is being converted into useful work in an AC electrical system. A low...
