Power Quality Challenges

What’s the most frequent power quality issues sufferred by most industries?

Market research

From worldwide customer surveys on the electric supply, it is
found that voltage dip is one of the PQ problems that causes
large inconveniences and has significant financial impacts to
various industrial process equipment;
(Consequences of Poor Power Quality – An Overview, Sharmistha Bhattacharyya & Sjef Cobben)
data suggest that across all business sectors, the economy
is losing between $104 billion and $164 billion a year to
outages and another $15 billion to $24 billion to PQ
phenomena

Impacts of Poor Power Quality

 waste of material / resources / work in progress;
 uncontrolled / inconsistent product quality;
 plant down time and delays in delivery time;
 increased wear / malfunction of electrical
component;
 reduced life expectancy / premature aging of the
equipment;
 additional labor (for product reworks, etc.);
 human health, safety, and productivity;
