Analysis of the discharge current of lightning arresters under typical lightning strikes can be carried out to determine the aging test of the lightning arrester and accurate life assessment by providing a waveform basis. But also to identify different types of lightning strikes, and to carry out targeted lightning protection measures. In this chapter, a PSCAD electromagnetic transient simulation model is constructed for a practical double-circuit 10 kV cable-overhead transmission line-cable typical configuration. The monitoring range of the lightning arrester discharge current monitoring device on the terminal tower under various lightning strike types is analyzed, along with the impact of lightning current amplitude and strike location on the waveform of discharge current at the terminal tower arresters. Additionally, the range of discharge current waveforms at terminal tower arresters under different lightning strike types is statistically compiled. The work in this chapter will provide a database for lightning arrester aging tests and lightning strike type identification.
