When is a voltage problem an actual case of poor power quality, and when is it instrumentation?
We received a data set this morning that seemed, on first glance to have spectacularly bad power.
However, if did not take long to realize we were on a Wild Goose Chase. Specifically, event waveshape graphs show arcing that is typically associated with a loose or intermittent connection, but no apparent impact on load current.
One of the benefits of having a live human being performing your power quality analysis – we spot these things in a way that automated report writers can not!
