01
What is Power Quality?
Power quality refers to the characteristics of the electrical supply that affect how equipment operates. Poor power quality includes voltage fluctuations, harmonics, and other distortions that reduce efficiency and damage equipment.
- Voltage sags and swells
- Harmonic distortion from non-linear loads
- Power factor issues
- Transients and electrical noise
02
The Hidden Costs
Poor power quality costs U.S. businesses an estimated $150 billion annually through energy waste, equipment damage, and production losses.
- 8-12% increased energy consumption from harmonics
- Premature equipment failure (motors, drives, electronics)
- Production downtime and quality issues
- Utility penalties for poor power factor
03
Identifying Power Quality Issues
Many power quality problems go undetected until equipment fails. Proactive monitoring can identify issues before they cause damage.
- Power quality meters and data loggers
- Thermal imaging for hot spots
- Motor current analysis
- Utility bill analysis for power factor
04
Mitigation Solutions
Various technologies can address different power quality issues. The right solution depends on the specific problems identified.
- Active harmonic filters for distortion
- Power factor correction capacitors
- Voltage regulators and UPS systems
- Surge protection devices
