Benifits Of PQ Monitoring

Why Monitor Power Quality ?

Power quality monitoring is an essential service many utilities perform for their industrial and key customers. Because of the technology and software now available, this monitoring is a highly-effective means to detect, solve, and even prevent problems on both utility and customer power systems. Not only can a monitoring system provide information about system disturbances and their possible causes, it can also detect problem conditions throughout the system before they cause customer complaints, equipment malfunctions, and even equipment damage or failure. Power quality problems are not necessarily limited to the utility side of the system - indeed, surveys have shown that the majority of power quality problems are localized within customer facilities. Given this, power quality monitoring is not only an effective customer service strategy, but also a way to protect a utility's reputation for quality power and service. In an industry facing increased competition, this reputation can be the difference between keeping and losing key accounts.
