The document discusses power quality issues and describes the Bill Zapper power conditioner. The Bill Zapper conditions power to protect equipment from common power problems like sags, surges, noise and poor power factor. It continuously monitors voltage and current and uses adaptive capacitor switching to improve power quality and reduce electricity costs by up to 30%. Key features include surge suppression, load monitoring and control, power factor correction and protection from over/under voltage, sags, noise and other issues.
