What is the basic concept of overvoltage? In the operation of various electrical equipment in power systems, besides withstanding normal system voltages, they also encounter various types of overvoltages. Overvoltages are generally classified into two categories based on their sources: external overvoltages and internal overvoltages. External overvoltages typically refer to lightning-induced overvoltages. Internal overvoltages refer to voltage increases caused by changes in system parameters due to circuit breaker operations, system faults, or other reasons, leading to the conversion or transfer of electromagnetic energy within the power grid.
