my.unimap-314432014-01-23T13:06:39Z Study of lightning back-flashover performance for 275/ 132kV transmission line by using ATP-EMTP Kiu, Ling Zee Noor Shahida Jamoshid Lightning- strike current Lightning stroke Transmission line Power system analysis Critical flashover voltage (CFO) Access is limited to UniMAP community. Direct lightning strokes to overhead transmission line towers or to shield wires may cause line insulation breakdown, due to the back-flashover phenomenon which the stroke builds up the voltages across the line insulation and if these voltages equal or exceed the line critical flashover voltage(CFO). Over-voltages which occur on the lines and travel toward the substation can cause damage, particularly to expensive equipment such as transformers, circuit breakers and so on. Thus, the study of lightning back-flashover performance for 275/132 kV Transmission Line has to be made by using ATP-EMTP (The Electromagnetic Transients Program). ATP (alternative transients program) is a universal program system for digital simulation of transient phenomena of electromagnetic as well as electromechanical nature. Demonstration of existed problems in power system can be made in this software and thus, help to solve the problem. Other aspects like tower grounding resistance and lightning current amplitude will be considered in this study as required. 2014-01-23T13:06:39Z 2014-01-23T13:06:39Z 2011-03 Learning Object http://dspace.unimap.edu.my:80/dspace/handle/123456789/31443 en Universiti Malaysia Perlis (UniMAP) School of Electrical System Engineering |
