Lightning surge protection devices are devices whose main objective is to protect electrical installations. They conduct to ground voltages that are above a safe threshold before reaching electrical appliances. Ideal lightning surge protection devices (SPD) should conduct the current at voltages higher than the rated voltage of the device, keeping the voltage stable for the duration of the surge but stopping the conduction as soon as the voltage returns to the rated value.
