While it does not matter whether it is a home, office or an industrial facility, an SPD can always be installed to help save valuable electronics and appliances from electrical surges. But the questions arise, what is a surge protection device, how does it function and what are its types? Let's try. Surge protectors (Surge Protective Devices, SPD) installed in distribution board panels are primarily used to protect electrical equipment from transient voltages (surges or spikes) caused by lightning strikes, power grid fluctuations, or other factors. Section 443 of BS 7671:2018+A2:2022 contains requirements for protection against transient overvoltages either of atmospheric origin or due to switching.
