In many cases when a local utility customer complains of voltage problems, it can often be traced back to a neighboring electrical load change that has caused voltage dips on connected services through their substation feeders.
One of the many utilities using PMI troubleshooting equipment brought to our attention such an incident.
Using properly installed power quality monitoring units, they were able to put together a timeline of events that made it possible to clearly identify the causes of voltage dips on low voltage circuits.
This case study examines this incident and the investigation of its cause.
