What is current carrying capacity of bundled conductor in relation to single conductor?
Wiki User
∙ 10y ago
Bundled conductors have a higher current carrying capacity compared to a single conductor of the same total cross-sectional area, due to improved heat dissipation. This is because the proximity of the conductors allows for more efficient cooling and reduces the overall resistance.

Temperature fell below -22 degrees celsius?
The temperature is extremely cold and potentially dangerous to be outside for extended periods of time. It is important to stay bundled up to avoid risk of hypothermia or frostbite. Consider staying indoors or limiting time spent outside.
What are fuel rods?
Fuel rods are long, slender rods containing nuclear fuel, such as radioactive uranium or plutonium isotopes, that are used in nuclear reactors to sustain a controlled nuclear fission chain reaction. These rods are grouped together in assemblies to provide the necessary fuel for the reactor to generate heat and ultimately produce electricity.
A picture of an element?
Fuel elements for PWR and BWR are described here (from Wikipedia) There is a picture shown but pictures don't reproduce on Wikianswers. Pressurized water reactor (PWR) fuel consists of cylindrical rods put into bundles. A uranium oxide ceramic is formed into pellets and inserted into Zircaloy tubes that are bundled together. The Zircaloy tubes are about 1 cm in diameter, and the fuel cladding gap is filled with helium gas to improve the conduction of heat from the fuel to the cladding. There are about 179-264 fuel rods per fuel bundle and about 121 to 193 fuel bundles are loaded into a reactor core. Generally, the fuel bundles consist of fuel rods bundled 14x14 to 17x17. PWR fuel bundles are about 4 meters in length. In PWR fuel bundles, control rods are inserted through the top directly into the fuel bundle. The fuel bundles usually are enriched several percent in 235U. The uranium oxide is dried before inserting into the tubes to try to eliminate moisture in the ceramic fuel that can lead to corrosion and hydrogen embrittlement. The Zircaloy tubes are pressurized with helium to try to minimize pellet cladding interaction (PCI) which can lead to fuel rod failure over long periods. In boiling water reactors (BWR), the fuel is similar to PWR fuel except that the bundles are "canned"; that is, there is a thin tube surrounding each bundle. This is primarily done to prevent local density variations from effecting neutronics and thermal hydraulics of the nuclear core on a global scale. In modern BWR fuel bundles, there are either 91, 92, or 96 fuel rods per assembly depending on the manufacturer. A range between 368 assemblies for the smallest and 800 assemblies for the largest U.S. BWR forms the reactor core. Each BWR fuel rod is back filled with helium to a pressure of about three atmospheres (300 kPa).
What are the types of cohesion?
Types of CohesionThe seven types of cohesion are as stated by (Ian Sommervile 1998):1. "Coincidental cohesion: The parts of a component are not related but simply bundled into a single component.2. Logical association: Components that perform similar functions such as input, error handling and so on are put together in a single component.3. Temporal cohesion: All of the components that are activated at a single time, such as start up or shut down, are brought together.4. Procedural cohesion: The elements in a component make up a single control sequence.5. Communicational cohesion: All of the elements of a component operate on the same input data or produce the same output data.6. Sequential cohesion: The output from one element in the component serves as input for some other element.7. Functional cohesion: Each part of the component is necessary for the execution of a single function".
Why 400kVA and above the transmission line have bundled conductor?
To reduce the electric field intensity at the surface of the conductor which can lead to corona discharge and insulation breakdown. By using bundled conductors, the electric field is distributed between the four (in the case of 400-kV lines) conductors, thus reducing the field intensity per conductor.
What is corona effect in?
Corona is a result of the ionization of a fluid around a conductor; when referring to electrical power lines, this is the ionization of the air around the conductor. At very high voltages (200kV and greater), this can become very significant, and can cause the deteriation of the conductor, or any conducting surface near the conductor, so special care is taken to mitigate it (such as using corona rings and bundled conductors). The ionization is a result of the buildup of electrons. Corona rings and bundled conductors provide a larger surface area for the electrons to "sit on".

What are the Advantages of bundle conductors in transmission lines?
High voltage transmission lines can transmit more power when the total impedance of the line is lowered. Inductive reactance is typically ten times larger than the series resistance of a conductor. Bundling drastically decreases the reactance of the largest component of impedance, the reactive inductance, and adding a second conductor also cuts real energy losses by one half because the resistance is reduced by one half. I squared X losses are reduced which means that the voltage drop along the line is reduced.AnswerThere is a limit to how much electric field intensity an individual conductor can withstand. This is greatest at the surface of the conductor. Even in dry air, ionisation may result causing corona discharge to take place, and may lead to a breakdown in insulation where the conductor is supported from its tower.Transmission line conductors, therefore, are bundled in order to reduce the electric field intensity which would be excessive if a single conductor were to be used instead. With bundled conductors, the same field is distributed equally between the bundled conductors, reducing the field intensity per conductor.

Explain capacitance of bundled conductor line?
Capacitors are formed by placing two conductors near each other. Usually, they are plates separated by an insulating dielectric. The capacitance is a function of the area and closeness of the plates. Bundled conductors have capacitance for the same reason - they are conductors close to each other. Since capacitors work by transferring charge (remember that the equation of a capacitor is dv/dt = i/c) then a signal on one conductor can induce a "copy" of the signal on the other line - usually a faint copy, but a copy nontheless. This induced voltage effect is also known as interference, and must be considered in the final system design.

What is corona effect in electrical?
When the distance between two conductors is more than that of the diameter and the potential difference is increased beyond the certain limit in such a way so that a glow ( seems like violet and shine ) is produced around the conductor and also noise is produced. This kind of effect called the Corona Effect in power systems. As the potential difference is increased, Corona Effect is also increased, and due to Corona Effect, Power loss in power system and disturbance in the nearer communication line is also increased.
