Electrical energy delivered from utility grids or generated by various sources often contains imperfections. These imperfections manifest as voltage spikes, sags, noise, and harmonic distortions, which can negatively impact the performance and lifespan of sensitive electronic equipment. The process of mitigating these unwanted elements to provide a stable and pure electrical supply can involve specialized equipment and techniques. For example, surge suppressors protect against transient voltage spikes, while line conditioners regulate voltage fluctuations and reduce noise.
The delivery of stable and consistent electricity is critical for the reliable operation of diverse applications ranging from residential appliances to sophisticated industrial machinery and sensitive medical equipment. Its importance extends to preventing equipment malfunction, data loss, and even potential safety hazards. Historically, concerns about power quality have grown with the increasing reliance on digital technologies, which are more susceptible to disruptions caused by compromised electrical supplies.
