Description : What is a high voltage test?

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.

Description : Why high voltage is used in power transmission?

Answer : The primary reason that power is transmitted at high voltages is to increase efficiency. ... The lower current that accompanies high voltage transmissionreduces resistance in the conductors aselectricity flows ... This means that thin, light-weight wires can beused in long-distance transmission.

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
