        "body_md": "> What are Voltage Dips or Sags?\n>\n> Voltage dips or sags are short-duration decreases in RMS voltage where the voltage levels return to normal levels after a given number of cycles or amount of time. This power quality-related event is commonly categorized by the duration and percentage decrease in the voltage level.\n\n> What causes a voltage dip or sag?\n>\n> Voltage dips are typically caused by faults in the power distribution system. These faults can be caused by naturally occurring events, such as lightning strikes, or created by man-made interference. Given the size and scale of the distribution grid, there are many types of faults that can cause voltage dips.\n"
