Study on Energy Absorption Characteristics of 220 kV Cable End Arrester

Taking 220 kV cable as the research object, the influence of some parameters, such as grounding resistance, lead inductance, source impedance ratio, and rated voltage of arrester on the energy absorption characteristics of arrester is studied under the condition of single-phase grounding at the end, and the selection of energy absorption capacity of arrester is discussed. The results show that the energy absorbed by arrester is significantly affected by grounding resistance and rated voltage of arrester. At the same time, the calculation results also show that the lower the rated voltage, the more energy the arrester can bear, and the higher the requirement for its energy absorption capacity.
