Power frequency withstand feature:

Due to various reasons such as single-phase grounding, long-line capacitance effect and load shedding in the power system, the power frequency voltage may rise or a transient over-voltage of a higher amplitude may be generated. The arrester has a certain power frequency for a certain period of time. The ability to increase voltage.
