What is the primary function of a TVSS/SPD?

The primary function of a TVSS (Transient Voltage Surge Suppressor) or SPD (Surge Protective Device) is to protect equipment from power surges. Power surges can occur due to various factors such as lightning strikes, utility switching, or sudden changes in electrical load, and these surges can cause significant damage to sensitive electronic equipment.

A TVSS/SPD works by diverting excess voltage away from connected devices, thereby safeguarding them from potential harm. This is crucial in maintaining the integrity and longevity of electrical systems and devices, especially in environments that are prone to transient voltage spikes. Understanding this function highlights the importance of surge protection in various applications, particularly in commercial and industrial settings where high-value equipment may be used.
