Power Quality & Harmonics

Stable, clean power is essential for efficient operations and the longevity of sensitive equipment. Our Power Quality & Harmonics solutions identify and eliminate electrical disturbances that cause overheating, malfunctions, or premature failure across industrial and commercial systems.

  • Harmonic Distortion Analysis (THD)

Detects distortion in current and voltage waveforms caused by nonlinear loads, helping mitigate overheating and resonance issues.

  • Power Factor Correction Studies

Optimizes capacitor placement and sizing to reduce reactive power demand, improve voltage stability, and lower energy costs.

  • Voltage Sag, Swell & Flicker Analysis

Identifies temporary voltage anomalies that affect sensitive devices and disrupt production processes.

  • Resonance Risk Assessment

Evaluates system conditions to prevent harmonic resonance, especially in the presence of capacitor banks and tuned filters.

What causes harmonics in a power system?

Harmonics are typically introduced by devices like variable frequency drives (VFDs), uninterruptible power supplies (UPS), LED lighting, and other nonlinear loads that draw current in short pulses rather than smooth sine waves.

How does power factor correction improve system performance?

By reducing the amount of reactive power in your system, power factor correction enhances voltage levels, increases capacity, and results in lower utility charges.
