Larger wire sizes (those with a greater diameter) will have less voltage drop than smaller wire sizes of the same length. He is member of Institution of Engineers (MIE),India. (reply) saravananOct 25, 2014Sir, Thanks a lot for sharing your experience .I want you to share your experience on factory electrical cable selection , DSL bus bar selection , cable size , current carrying capacity of cable , mcb selection (reply) Engr Muhammad TanveerOct 22, 2014Sir, Thanks a lot for sharing your experience .I want you to share your experience on building electrification of high rise buildings and what are the factors that as electrical engineer you should be considered. Shorter wires will have less voltage drop than longer wires for the same wire size (diameter). All this sounds terribly abstract, but it's really not much different from water running through a garden hose. It is recommended that the voltage drop should be less than 5% under the fully loaded condition. why dint you apply the actual current rating for the cables viz 170,200 A respectively.I mean these are the cables we are selecting so why not use their rating in the formula?? Pls explain (reply) JAIPAL SINGHJul 17, 2015KINDLY CONFIRM HOW TO DO THE HIGH VOLTAGE TESTING OF 33KV CABLE OF 16KM LENGTH. Still another critical factor in voltage drop is wire length. Membership No:M-1473586.He has more than 13 years experience in Transmission -Distribution-Electrical Energy theft detection-Electrical Maintenance-Electrical Projects (Planning-Designing-Technical Review-coordination -Execution).

The ampacity of a wire depends on a number of factors. According to IEEE & BS 7671 (2011), derating current = design current Ib / total derating fator Kt. I want you to shed more light on the relationship between, design current, total derating factor, derating current and cable current carrying capacity. Ground temperature is approximate 35 Deg. Experts say that voltage drop should never be greater than 3 percent.
