Common Issues Uncovered by a Power Quality Audit
A power quality audit can uncover a range of common issues that may be affecting the performance of an electrical system. One common issue is voltage sags, which are temporary reductions in voltage levels that can cause equipment malfunctions or disruptions to production processes. Voltage swells, on the other hand, are temporary increases in voltage levels that can also lead to equipment damage or failures. Both voltage sags and swells can be caused by various factors, such as utility grid disturbances or internal issues within the facility’s electrical system.
Another common issue uncovered by a power quality audit is harmonics, which are unwanted frequencies that can distort voltage waveforms and cause interference with connected equipment. Harmonics are often generated by non-linear loads, such as variable frequency drives or electronic ballasts, and can lead to overheating, increased energy consumption, and reduced equipment lifespan. By identifying and addressing harmonics through a power quality audit, facility managers can minimize these negative effects and improve the overall performance of their electrical systems.
In addition to these common issues, a power quality audit may also uncover other disturbances such as transients, flicker, or frequency variations that can impact the reliability and efficiency of connected equipment.
