A voltage dip, also known as a voltage sag, is a temporary reduction in voltage levels in an electrical system. This phenomenon typically lasts for a few milliseconds to several seconds and can occur due to sudden increases in load, short circuits, or equipment malfunctions. Voltage dips can affect the performance of sensitive electronic devices, leading to disruptions or malfunctions. These dips are often measured in percentage terms, indicating how much the voltage has dropped from its normal level. For example, a voltage dip of 30% means the voltage has decreased to 70% of its standard value. Understanding voltage dips is crucial for maintaining the reliability of electrical systems and protecting equipment from damage.
