In the field of electronic circuits, surge is a common and potentially harmful phenomenon. Surge, in simple terms, refers to the momentary and intense voltage or current fluctuations that occur in a circuit.
Surge, as the name suggests, refers to a voltage or current peak that occurs instantaneously and exceeds a stable value. In electronic circuits, surges typically manifest as brief and intense pulses, with a duration of only a few millionths of a second. This pulse may be caused by various factors, such as the start-up of heavy equipment, short circuits in circuits, power switching, or the operation of large engines.
