Vital Considerations for Power Factor Correction

This comprehensive technical workshop explains critical factors to be
considered when designing power factor improvement equipment that
will stand the test of time. Knowledge gained and techniques learned will
help you to design long lasting PFC equipment and to quantify the key
parameters necessary for ideal component selection.
Methods of analysis and formulae are shared plus typical examples are
worked through together. The workshop is taught by an instructor who
has 40 years of experience in the design, application and analysis of
power quality problems and equipment.
Upon completion, participants should have a broadened understanding of
many factors that need to be considered when designing an engineered
power factor system.


The 8-hour technical workshop explains key factors affecting capacitor life and methods to consider in the design of modern PFC systems. This course explains how system conditions (such as harmonics) can have  an adverse effect on capacitors and enclosure heating. It teaches methods of power system analysis to quantify the effects of harmonics for ideal capacitor selection and their effect on heat generation. It also covers the nuances of fixed, automatic and hybrid PFC systems, kVAR step optimization, and various application considerations.

Introduction & Key Capacitor Factors

Voltage (Peak & RMS)



Basic System Requirements


Fixed, automatic, hybrid

Capacitor stages vs steps

Harmonic & Harmonic Resonance Analysis

Background voltage & current distortion

Series & parallel resonance paths

Power System Harmonics vs. Capacitors

Capacitor current

Capacitor voltage

Application considerations


Upon completion of this course, participants should have a meaningful understanding of the various types of power factor, the impact that low power factor has on electric power systems, the causes of low power factor, methods to analyze power factor and methods to improve power factor.

This course is applicable to electrical industry professionals serving either industrial or commercial environments. For maximum benefit of this course, participants should have an understanding of basic electrical principles such as Ohms law, power, electrical metering, motors and general electrical equipment and systems.  Visit our Seminar Schedule for the next scheduled Power Factor Seminar.  (4 PDH)
