Frequently Asked Questions
What causes power quality problems?
Power quality issues typically result from non-linear loads such as variable frequency drives, UPS systems, LED lighting, computers, and electronic equipment. These loads draw non-sinusoidal currents that create harmonic distortion in the electrical system.
How do I know if my facility has power quality issues?
Common symptoms include equipment overheating, nuisance tripping of circuit breakers, transformer humming, capacitor failures, motor vibration, and unexplained equipment malfunctions. Power quality analysis can identify and quantify specific issues.
What is the difference between AHF and SVG?
Active harmonic filters (AHF) primarily address harmonic distortion by injecting compensating currents. Static VAR generators (SVG) primarily provide reactive power compensation for power factor correction. Some facilities require both technologies for comprehensive power quality improvement.
Do capacitor banks still make sense with harmonic issues?
Traditional capacitor banks can be problematic in harmonic-rich environments due to resonance risks. Detuned reactor systems or SVG technology are often better choices for facilities with significant non-linear loads.
What UPS topology is best for critical loads?
Online double-conversion UPS systems provide the highest level of protection by continuously conditioning power through the UPS regardless of utility conditions. This topology is recommended for sensitive IT equipment, medical devices, and critical process control systems.
How often should UPS batteries be replaced?
VRLA battery life typically ranges from 3 to 5 years depending on operating conditions. Regular battery testing helps identify degradation before failure. Lithium-ion batteries generally have longer service life but higher initial cost.
Can power quality issues affect my electricity bill?
Yes. Low power factor results in utility penalties in many jurisdictions. Additionally, harmonic distortion increases losses throughout the electrical system, resulting in higher energy consumption for the same useful work.
What standards apply to power quality?
Key standards include IEEE 519 for harmonic control, IEC 61000 series for electromagnetic compatibility, and EN 50160 for voltage characteristics. Specific requirements depend on utility interconnection agreements and local regulations.
