Electrical transients are short-lived bursts of electrical energy that occur in a circuit when there is a sudden change, such as a switch being turned on or off, or a lightning strike. These rapid changes can cause voltage spikes or dips, which may lead to equipment malfunction or damage if not properly managed. To mitigate the effects of electrical transients, devices like surge protectors and transient voltage suppressors are often used. These tools help absorb or redirect excess energy, protecting sensitive electronics and ensuring the stability of electrical systems in homes and industries.
