Invest in surge protective devices to protect your equipment. Power surges can happen anywhere, but 60 to 80% of them originate from equipment inside our buildings. Power surges can be caused by switching electrical loads from contactors, relays, and breakers, as well as the switching of capacitor banks, like power factor correction. Discharge of inductive devices, such as motors and transformers, can also cause surges as well as faults or arc initiations: https://lnkd.in/gYtxwNMh
