Measure Lightning-induced Voltage Dips in a Low-Voltage Circuit

There is no way to avoid a voltage dip caused by lightning hitting a high-voltage system. This also causes a voltage dip in the low-voltage circuit so utility users need to take measures.
A dip event function of the PQ3198 Power Quality Analyzer is useful in detecting a voltage dip. The dip event function detects a voltage dip when the voltage RMS value falls below the threshold.
When a dip event occurs, it records the changes in the RMS value during a period of 0.5 s before the event and during a period of 29.5 s after the event and the instantaneous waveforms during a period of 200 ms when the event occurs.
