Read how to find the source of a sag and techniques for voltage sag mitigation.


The first step in voltage sag mitigation is finding the source of the sag. In a power quality recording, spotting the voltage sag itself is often easy, but determining whether the sag was caused by a load being monitored (downstream), or incoming from the distribution side (upstream) requires a closer look at the data.


Techniques for determining the sag location are described in this whitepaper, along with examples.
