A report published in Industrial Safety and Hygiene News estimated that, on average, there are 30 000 arc flash incidents every year. The report went on to estimate that those incidents resulted in average annual totals of 7 000 burn injuries, 2 000 hospitalizations, and 400 fatalities per year.
Partial Discharge is more common than we like to believe. There are ready technologies available that help to not only reduce the risk of arc flash exposure, but also, simultaneously, enhance the overall reliability of the electrical system. It’s really a win‐win for safety and reliability.
There are a few technologies available, but some are better than others. Some are suited for a particular purpose. It’s a case of choosing the right one, for the right applications, on the right components, on the right situation.
When compared, ultrasound seems to be the most practical, simple, comprehensive and cost‐effective. Ultrasound should be your first line of defense technology to build out your overall electrical condition monitoring and analysis strategy.
