Description : Why high voltage test is done?

Description : What is Extra High Voltage?

Description : What are the advantages of high voltage transmission?

Answer : Advantages:  1. As Transmission voltage increases, current decreases. 2. As current decreases, cross section of conductor decreases. 3. As cross section of conductor decreases ... line increases  12. As transmission voltage increases power handling capacity of transmission line increases 

Description : What is considered low voltage and high voltage?

Description : Why high voltage can reduce power loss?

Answer : when voltage has increased due to reduced current flow, thus power loss given by ( I^2R) will be low due to reduced current(I^2) provided that resistance (R) is constant.
