Over voltages are phenomena which occur in power system networks, either externally or internally. The selection of certain level of over voltages which are based on equipment strength for operation is known as insulation coordination. A study has been carried out to investigate over voltages due to lightning, which is affecting an air insulated substation (AIS). The objective of this study is to determine whether the withstand capability or the Basic Insulation Level (BIL) is the cause of fault occurring in a substation © 2012 IEEE.

This paper presents the analysis of lightning arrester energy due to back flashover and shielding failure phenomena in a 132kV transmission line in Malaysia. The transmission line, towers and surge arresters were modeled using PSCAD/EMTDC software. The model has been used to simulate the discharged energy from lightning arresters that were installed on the tower in the event of back flashover and shielding failure. The arrester was modeled based on the IEEE frequency dependent model. Comparison between the simulation results and values calculated theoretically was performed to validate the model that has been developed. The results show that both are in reasonable agreement with each other. The maximum calculated and simulated energy discharged by the arrester is found to be less than 5.1 kJ/kV, which is the rating of arresters installed in the actual 132kV transmission lines. © 2012 IEEE.

This paper presents analysis of lightning arrester energy due to back flashover and shielding failure for the purpose of installing transmission line arrester (TLA). This study simulated, analysed and validated with the installed lightning arresters on the 132kV transmission line in Malaysia by using PSCAD/EMTDC software. The arrester is based on IEEE frequency dependent model. The simulation result shows that the lightning arrester energy obtained through simulation is less than the rating installed at site © 2012 IEEE.
