Voltage sag, also known as voltage dip, is a short-term reduction in voltage levels that typically lasts from a few milliseconds to a few seconds. It is commonly caused by sudden increases in load demand (such as the starting of large motors), short-circuit faults, or other disturbances in the electrical system. This phenomenon can result in equipment malfunction, tripping of circuit breakers, and may impact sensitive electronic devices.
