摘要： Embodiments of the present disclosure relate to a method and electronic apparatus for predicting residual lifetime of a voltage limiting element. The method comprises: receiving current sensing signals representing currents flowing through a voltage limiting element within overvoltage period; determining, based on the current sensing signals, overvoltage parameter values of overvoltage parameters within the overvoltage period; and determining, based on a length of the overvoltage period and the overvoltage parameter values, residual lifetime of the voltage limiting element using an overvoltage model of voltage limiting element. The technical solutions in accordance with embodiments of the present disclosure enhance the precision for predicting residual lifetime of the voltage limiting element.
