Optimization of Cable Length in Transmission Line - Cable Fed G.I.S System
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 8
Abstract
Transmission line cannot be directly terminated with connection to GIS, hence we use cable for termination of transmission line and connect to GIS , the problem is how much length of cable to be used Short length are generally not preferred and long length of cable will lead to raise in voltage levels because of capacitance . This paper deals with finding the best possible cable length for transmission line termination. EMTP software is used to simulate this system and observe results to decide on the best possible length of the cable used. (Generally we use XLPE cables). 400kv -Transmission line of 100 km is considered and a 400kv XLPE cable is selected for the study. Study on this system is done by giving impulse voltages (both switching and lightning impulse) for the circuit and observing the voltage levels at transmission line end and cable end.
