Impedance Inversion in Microwave circuits can be obtained by utilizing the Short Circuit or Open Circuit Transmission line of proper length.


How many wire are used in transmission line?

Transmission lines are three-phase systems. There are three line conductors in a three-phase system. However, to reduce electric stress at higher voltages, these lines are frequently made up of 'bundled' conductors -so each line might have two, three, or four separate conductors. In addition, transmission towers usually carry separate circuits -i.e. separate three-phase circuits on opposite sides of each tower. So, in the UK for example, a typical 400-kV transmission line will consist of two, separate, three-phase circuits suspended on each side of each tower, with each line consisting of four bundled conductors. That's 24 conductors.


Why you go for multi-conductor system in power transmission?

All a.c. transmission systems are three-phase systems, which comprise three line conductors which are suspended from towers. Each 'line' is generally made up of a number of 'bundled' conductors -according to the transmission voltage- to reduce the electrical stress. Many transmission towers carry two separate three-phase circuits, one on each side of the tower.

Yes so the pump fills the circuits otherwise you get a false full reading.


Why star connection used in transmission?

Transmission circuits are prone to earth faults.Only star connection permits flow of earth fault current and the operation of earth fault relays.


What is the P0753 code for a Dodge Durango?

The ECU fault code PO753 refers to the Transmission 3rd to 4th gear Shift Solenoid. This is part of the Transmission Relay Circuits. To repair this will require knowledge of the transmission. I suggest unless you are knowledgeable you take this to a transmission professional for repair.
