Measure Voltage Drop Caused by Wiring Impedance

A longer and thinner wire results in a larger drop in load voltage caused by wiring impedance in relation to the power supply voltage, which will have an impact on other equipment.
A dip event function of Hioki’s Power Quality Analyzer PQ3198 is effective in detecting a voltage drop.

PQ3198 detects the dip event when the voltage RMS value falls below the threshold value.
When a dip event occurs, the PQ3198 records changes in the RMS value during a period of 0.5 second before the event and during a period of 29.5 seconds after the event, as well as instantaneous waveforms during a period of 200 ms when the event occurs.
