Voltage stabilizers and filters

Modern industry is becoming more automated and the sensitivity of processes to power quality events is increasing.

It is generally recognized that quality is an important aspect of the electricity service. Not only low prices are important, also high-quality matters to customers. Price and quality are often complementary aspects; together they define the value that customers derive from consuming electricity.

In practice the voltage is never perfect.

If the quality of electricity supplied to the plants drops below a certain level, equipment no longer works properly and customers are likely to experience problems. Sensitive industry sectors may incur a Power Quality cost up to 4% of their turnover, with about 60% of those costs caused by voltage sags and short interruptions.
