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.

This paper presents a study on flashover patterns due to double tripping using EMTP software. The simulation was performed on a 132 kV line double circuit for economic installation of transmission line arresters (TLAs). The simulation results were validated with the field data of 132 kV transmission line in Malaysia. A vertically configured double circuit transmission line was modelled and the effects of tower footing resistance, lighting current values, power frequency voltage and the coupling effect of the phase conductors study were taken into account. A good agreement between the simulation and field data was obtained. A specific back flashover phase of the double circuit line can be determined by considering the effects that have been mentioned. Through determination of the tripping pattern, a suitable installation of line arresters and mitigation of line tripping due to back flashover can be achieved. © 2012 Elsevier Ltd.
