The Truth Behind PQ Solutions and Energy Savings Pointing out the pitfalls associated with overstated marketing claims on power quality devices that promise excessive energy savings

摘要

One of the most significant changes in the power quality industry in the past five years has been the method of selling power quality (PQ) solutions. Originally, PQ solutions were sold as an insurance policy to avoid potential damage from power disturbances, such as transients, voltage sags, interruptions, or harmonics. Today, many PQ solutions providers have found it more effective to promote energy cost reduction associated with their products rather than to deal with the soft savings associated with minimizing downtime or reducing damage to electrical equipment. The problem is some of these solutions providers have significantly overstated the savings. While these solutions can provide excellent protection, they often provide very little, if any, energy savings.
