PF Correction
PF Correction Basics
The current absorbed by an AC load has two components: the active component, which does useful work, and the reactive component, needed for the electrical and magnetic fields that make that work possible. This article covers power factor, the ratio between the two, and the formulas used to size correction equipment.

Hybrid Panels
With the growing use of non-linear loads and KVAh billing now in force in several states, correcting only the fundamental reactive power with capacitor banks isn't enough — the distortion component needs harmonic filtration too. Hybrid panels combine both functions in a single unit.

Harmonic Basics
Harmonics affect the quality of AC power delivered to industrial, commercial and residential facilities — raising energy costs, shortening equipment lifespan, and in some cases overheating conductors enough to create a fire risk. This article explains what harmonics are and why they matter.
