The document discusses issues related to power quality that can negatively impact industries. It notes that irregularities in power supply can cause problems like worn out motors, lost data, erroneous robot movement, downtime, and increased maintenance costs. It presents two types of solutions: utility-based solutions like FACTS devices controlled by utilities, and customer-based solutions like custom power devices controlled by customers. Reliable power is important for modern manufacturing equipment, and power quality issues can cause shutdowns that result in economic losses. While utilities can cause problems, many issues happen within industries due to non-linear loads causing disturbances.
