Transmission lines are current-carrying lines that transport power from generating stations to substations. Feeder is a distribution network of electrical power. They transport electricity from a substation to consumers. A feeder is a line that starts from the grid and connects to whom we want to send power to consumers.
What is feeder in transmission line?
Substation feeder definition. A feeder carries energy to a substation or bus or to several loads. The several substation feeder arrangements are discussed in this technical article. Feeder may connect two substation buses in parallel to provide stiffness or service continuity for the load supplied from each bus.
What are the three types of transmission lines?
The types of transmission lines are: Overhead Transmission Lines. Subtransmission Lines. Underground Transmission Lines.
What is the difference between the transmission line and distribution line?
Transmission lines are used for carrying electric power from power stations to the substations. Distribution lines are used for carrying the electricity from substations to load points such as home, businesses, industries, etc.
What is the difference between feeder and service Main?
It is a conductor which connects between generating stations to the area of the where power supply requires. The cross section area of feeder is determined by considering current passes through it.
Are transmission lines AC or DC?
ACTransmission lines mostly use high-voltage AC (alternating current), but an important class of transmission line uses high-voltage direct current. The voltage level is changed with transformers, stepping up the voltage for transmission, then reducing voltage for local distribution and then use by customers.
What are transmission lines called?
Types of transmission line include parallel line (ladder line, twisted pair), coaxial cable, and planar transmission lines such as stripline and microstrip. The higher the frequency of electromagnetic waves moving through a given cable or medium, the shorter the wavelength of the waves.
What is difference between feeder and distributor?
The distributor is a conductor which distributes the electrical power in particular area. A feeder has no tapping on it. It has a number of tapping on me through which the electrical power is actually reached to consumer premises. Current through it always remains same.
What are the 3 types of power supply?
Linear, Switched, or Battery-based? There are three subsets of regulated power supplies: linear, switched, and battery-based. Of the three basic regulated power supply designs, linear is the least complicated system, but switched and battery power have their advantages.
Why do power lines have 3 wires?
Advantages. As compared to a single-phase AC power supply that uses two conductors (phase and neutral), a three-phase supply with no neutral and the same phase-to-ground voltage and current capacity per phase can transmit three times as much power using just 1.5 times as many wires (i.e., three instead of two).
What is a feeder?
Definition of feeder 1 : one that feeds: such as. a : one that fattens livestock for slaughter. b : a device or apparatus for supplying food.
What does Feeder mean in electrical?
A feeder is the circuit conductors between the service equipment, the source of a separately derived system, or other power source and the final branch-circuit overcurrent device. Conductors past the final OCPD protecting the circuit and the outlet are branch-circuit conductors [Art.
How are transmission lines classified?
Transmission lines carry high voltages from the generating stations to primary transmission stations, secondary transmission stations, primary distribution stations, and secondary distribution stations. These lines are classified based on their location (overhead or underground), length, and voltage rating.
How many types of power transmission lines are there?
Two common types of transmission line are coaxial line (Figure 3.2. 1) and microstrip line (Figure 3.2. 2).
How many types of electrical transmission are there?
Fundamentally there are two systems by which electrical energy can be transmitted: High voltage DC electrical transmission system. High AC electrical transmission system.
What are the types of power transmission?
There are four main types of power transmission – mechanical, electric, hydraulic and pneumatic.
How many types of transmission towers are there?
4 Different Varieties Of Transmission Towers With Respect To Their Applications.
How are transmission lines and feeders similar?
Another similarity I find between transmission lines and feeders is that both are designed considering the current capacity of conductors since Voltage regulation doesn't matter *much* in bulk transmission and no tappings are taken out in feeders so voltages tends to remain same .
What is a transmission line?
Transmission line: It is a structure used in electric power transmission and distribution to transmit electrical energy along large distances. It consists of one or more conductors (commonly multiples of three) suspended by towers or poles. Since most of. Continue Reading.
What is a feeder in a generator?
Feeders: These are the conductors which are of large current carrying capacity.The feeders connect the substation to the area where power is to be finally distributed to the consumers.No tappings are taken from the feeders.The feeder current always remain constant.The voltage drop along the feeder is compensated by compounding the generator.
What is a feeder?
Feeder is network of conductors which feeds power in different localities from sub-station usually at 11kv. It makes power reach near the consumers where 11kv is stepd down to 230/440v for uses.According to purposes and requirements feeders are divided into four groups 1. Radial feeder 2.Ring Feeder 3.
What is line voltage?
Line voltage, line to line voltage, or phase to phase voltage: The voltage (whether instantaneous, phasor, RMS value, or amplitude/peak value) across two lines of a three-phase element (i.e. a three-phase motor, three-phase generator, three-phase transformer, three-phase capacitor bank, three-phase static load) or of a three-phase transmission or distribution line. In phasor form, they’re denoted as V ~ L or V ~ LL.
What is a feeder in a power system?
Feeder are the power lines through which a electricity is transmitted in power system .The term electrical feeder is distributed through electrical system and transmission are the specalized cable and it is used for cable such as connecting distributing cable television signals. 921 views.

How does generator power get transmitted to load center?
Generated power get transmitted to load center at EHV voltage levels through “TRANSMISSION LINES”. At load centers voltage reduced to HV level and get feed to consumers and distribution transformers by “FEEDERS”
