Introduction
Reactive Power Compensation and Harmonic Mitigation Solutions
How can reactive power compensation and harmonic mitigation solutions be part of your energy efficiency programs?
Power factor is a measure of how efficiently you are using electricity. In an electric power system, a load with low power factor draws more current than a load with a high power factor for the same amount of real power transferred. Utility customers with a low power factor could realize an increase or penalty in their electric bill. Over time, these penalties may reach into thousands of dollars, depending upon the utility’s rate structure.
Harmonics may disrupt normal operation of other devices and increase operating costs. Symptoms of problematic harmonic levels include overheating of transformers, motors and cables, thermal tripping of protective devices, logic faults of digital devices and drives. Harmonics can cause vibrations and noise in electrical machines (motors, transformers, reactors). The life span of many devices can be reduced by elevated operating temperature.
As a leader in the field of power quality, Schneider Electric offers the products and services needed to ensure that the most reliable and cost effective solution is applied within your facility. We can help you select the right solution for your application, for greenfield or brownfield projects. Please visit us at https://www.se.com/us/powerandenergy.

It integrates conventional power factor correction systems and the latest IGBT-based solutions to provide ultra rapid response and infinitely variable kVAR control. |
PowerLogic™ PFV+ |
Power Factor Correction |
Provides reactive current compensation for specific and high performance systems. It can eliminate leading or lagging power factor, reduce voltage fluctuations, enhance equipment operating life, and improve system power capacity. |
PowerLogic™ PCS+ and PCSn |
Power Factor Correction and Harmonic Filtering |
It is a flexible, high performance, cost-effective solution to stabilize electrical networks by providing harmonic mitigation, power factor correction, and load balancing. It monitors a distorted electrical signal and determines the frequency and magnitude of harmonics in the signal. It cancels the harmonic content with the dynamic injection of opposing phase current in the distribution system or individual load. |
