Why we choose 400kv,220kv,132kv,66kv,33kv transmission
voltages for transmitting power. Why not other voltage
levels.
Answer Posted / engineer
form factor is not the cause..else we would have 9.9 kv line system also...so nothing to do with dat..its all about the transmission system equipments,whih are designed for the voltage levels of 6.6,11,33,66,etc

if an insulated power and control cables of a running gas diesel gensets laid direct in an open trench i.e, trench bed is not rcc of a power house in which rain water, spillage water alwas exists and all power control cables remains submerged even when gas gensets of 480 kw each runningin on load. These power &control cables runs from power house to switchgear room through these trenches in which water remains most of the time. pl explain its merit & de-merit
