Yes of course,they can be distinguished mainly by their voltages because that's the main significant difference between both systems. The transmission voltage levels are 330KV for the grid transmission; 132KV for the sub-transmission lines. The 33kV, 11KV and other lower voltages constitute the distribution system. I hope this helps! �� Pls feel free to correct this if I'm wrong.

Williams61. : Transmission lines are for large distances, their voltage is higher, and they can transport more electricity. You can see them on the side of the freeway for example. Distribution lines are for short distances, their voltage is lower, and they transport electricity locally. You can see them on the side of the street.
ReplyDeleteMerely by voltage level NO... BECAUSE
ReplyDeleteTransmission lines are for large distances, their voltage is higher, and they can transport more electricity. You can see them on the side of the freeway for example.
Transmission lines go from power plants to substations at a high voltage. They can bring electricity from one end of the country to the other, using interstate connections. There can also be transmission lines between countries.
WHILE
Distribution lines are for short distances, their voltage is lower, and they transport electricity locally. You can see them on the side of the street. Distribution lines are low voltage lines which bring electricity from substations to your home. The lines are smaller, and cover shorter distances.
YES, I think so because
ReplyDeleteToday, transmission-level voltages are usually considered to be 110 kV and above. Lower voltages, such as 66 kV and 33 kV, are usually considered subtransmission voltages, but are occasionally used on long lines with light loads and Voltages less than 33 kV are usually used for distribution.
yes they can be distinguished , it is the voltage level that makes the difference between transmission line and distribution lines, transmission line voltage is higher than distribution line , because transmission line is coming directly from the power generating station
ReplyDeleteYes because it can be used to show deiffrences between Distribution networks and transmission line networks their voltage level and topology. Lower voltage is used in distribution network, as lower voltages require less clearance. Typically, lines up to 35 kV are considered part of the distribution network.
ReplyDeleteDistribution system are distinguished from transmission system by their voltage level and topology. Distribution system carries electricity from the substation to the consumer's end as lower voltages require less clearance ,up to 35 kV are considered in the distribution system while the transmission system helps in the movement of electricity from a power plant or power station to the various substations and operates 66 kV for high voltage, and 11 kV for medium voltage.
ReplyDeleteNo. Transmission and distribution systems can be distinguished by their voltages in which transmission system Carries electricity at a very high voltage About 11000 volts . While distribution system Carries electricity at a very low and safe level of about 220 volts. But there are other ways to distinguish them like the basic usage of the transmission and distribution system, their working supply phase, and level of conduction.
ReplyDeleteThey can be distinguished from their voltages.

voltage levels are not the only properties that distinguishes a transmission system from a distribution systems. Here are other differences;
1.Transmission systems are for long distance while distribution systems are mainly for short distance.
2. Transmission systems are mainly in 3phase while distribution systems can be either single phase or 3phase.
3. Transmission systems are always situated far away from habitted areas, while distribution systems can be made to run locally through the the streets, city.
4. Transmission systems convey bulk of electricity from the generating station while distribution systems convey a moderate voltage of electricity from the substation to reach the consumer
5.The transmission lines do carry conductors on both arm of the tower in case there is a failure, while a distribution line does not.
Yes. Distribution networks are distinguished from transmission networks by their voltage level and topology. Lower voltages are used in distribution networks, as lower voltages require less clearance. Typically, lines up to 35 kV are considered part of the distribution network.
ReplyDeleteWhile
Higher voltages are used in transmission system.
Yes, they can be distinguished because a Transmission lines is a high voltage line that carries electricity from power plant to the substation from which it is further distributed to various areas for different purposes. Distribution lines are low voltage lines that carry electricity from the substations to the end users for residential and commercial use.
ReplyDeleteTherefore, Transmission lines carry electricity at a very high voltage that is of about 11000 volts whereas Distribution lines carries electricity at a very low and safe value level that is about 220 volts.

Yes because one of the main difference between distribution system and transmission system lies in the power transfer capability and distance
ReplyDeleteAnd transmission system are designed to transfer large amount of power over a long distance (high voltages)
And distribution systems are designed to transfer small amount power over a short distance to the consumer (low voltage)

ReplyDeleteNo,it can
Rebecca 39
ReplyDeleteYes but it can also be distinguish from each other by their thickness,phase.The voltage of transmission line is very high and at 11000 volt while that of distribution system is very low and it at 220 volt
Yes because it can be used to show deiffrences between Distribution networks and transmission line networks their voltage level and topology. Lower voltage is used in distribution network, as lower voltages require less clearance. Typically, lines up to 35 kV are considered part of the distribution network.
ReplyDeleteAdegun03
ReplyDeleteYes, they can be. voltage level is a MAJOR distinguisher between transmission line and distribution system. Because transmission lin transmits a voltage as high as 66KV while distribution system distributes a voltage as moderate as 210 -240 volt, depending on the country. So owing to this voltage levels other factors of differentiation can now surface. But their voltage level is what majorly distinguish them.
No.
ReplyDeleteTransmission and distribution line are distinguished basically by their voltage. But there are other ways to distinguish them: Current conduction level, usage, phase, thickness. And these ways of distinguishing them should not be neglected.
Truly they can be distinguish by voltage.
ReplyDeleteAnd also by their distance and thickness of cables as well.
Transmission lines are for large distances, their voltage is higher, and they can transport more electricity.
Transmission line are bi-direction while distribution line are mono direction.
The voltage of transmission lines can go anywhere from 69 kV up to 765 kV While the voltage of distribution lines varies between 4KV and 69KV.
The power poles of transmission line are higher and cables are thicker than distribution lines.
I concluded that voltage is the major factor to be considered first while others follows.
The transmission systems are always situated far away from habitted areas, while distribution systems can be made to run locally through the the streets, city.
ReplyDeleteTransmission lines go from power plants to substations at a high voltage. They can bring electricity from one end of the country to the other, using interstate connections. There can also be transmission lines between countries.
The high-voltage transmission system (or grid) transmits electric power from generation plants through 163,000 miles of high voltage (230 kilovolts [kV] up to 765 kV) electrical conductors and more than 15,000 transmission substations. The transmission system is configured as a network, meaning that power has multiple paths to follow from the generator to the distribution substation
ReplyDeleteThe distribution system contains millions of miles of lower voltage electrical conductors that receive power from the grid at distribution substations. The power is then delivered to 131 million customers via the distribution system. In contrast to the transmission system, the distribution system usually is radial, meaning that there is only one path from the distribution substation to a given consumer
High voltage
ReplyDeleteThe voltage of transmission lines can go anywhere from 69 kV up to 765 kV. The power poles are higher and cables are thicker than ditribution lines.
Bi-directional
Transmission lines are bi-directional: the electricity can go in both directions. This is a necessary feature for the balance of the grid. In wholesale electricity markets, electricity flows from areas of generation to areas of demand. But these areas of demand may change over time, so the electricity will travel in different directions.
Maintenance
Transmission networks require operating more actively than distribution networks. Maintenance must be done through automatic and manual interventions.
distribution2
Distribution lines are used for local electricity delivery.
Distribution lines
Distribution lines are low voltage lines which bring electricity from substations to your home. The lines are smaller, and cover shorter distances. The whole distribution network in the US is not directly connected: they are connected through the substations which connect them to the transmission network.
Low voltage
The voltage of distribution lines varies between 4KV and 69KV.
electric pole transformer
The cylindrical box is a secondary transformer, which brings the voltage down to 120V or 240V.
Mono-directional
Distribution lines in the US are traditionally made only to travel in one direction. Therefore the distribution network was not initially designed to accommodate generation. But since distributed generation has started to be implemented on grids worldwide, smaller generation facilities (wind turbines, solar panels, and other localized power generators) are plugged on the distribution network. This causes more stress on the distribution grid, and it is required to renew this grid in some cases, to make it more efficient for these new methods of generation
Maintenance
As compared to transmission lines, distribution lines are passive systems, (they are not actively managed by operators or computer programs). Also, since they are traditionally unidirectional in power flow (from high voltage to low voltage), they do not require much maintenance. This has started to change in areas where distributed generation is implemented.

transmission
There are 2 different types of electric lines for the transportation of electricity.
Transmission lines are for large distances, their voltage is higher, and they can transport more electricity. You can see them on the side of the freeway for example.
Distribution lines are for short distances, their voltage is lower, and they transport electricity locally.
Power travels from power sources to residential, commercial and industrial customers. During this, the electricity goes through transmission lines and distribution lines. From one type of line to another, the electricity goes through transformers which modify the voltage in order to optimize the energy lost through electromagnetic fields.

Well....
ReplyDeleteVoltage level is is part of but not what distinguishes them. There are some other factors that needs to be put to consideration such as:
1. Usage:- transmission line is meant to carry electric power from power plants to substation which distribution is from substation to consumer end
2. Phase:- transmission functions only in 3 phase while distribution in single phase
3. Thickness:- transmission line is usually thicker while distribution is thin
4. Current condition:- transmission conduct current at voltage beyond 69kv while distribution at voltage below 69kv.
While the voltage level aspect is just
Transmission at 11kv or more per phase and distribution is only 220v per phase
Yes it can be distinguished by their voltage. Firstly transmission system are of higher voltage, it's design for to move large amount of power over a long distance, and it's typically from 69kV up to 765kV.
ReplyDeleteWhile distribution system are of lower voltage, it's purpose is to distribute the electricity on a localized area, our homes and offices. The distribution System typically operates in a voltage range of 4kV up to 64kV
BAMIKOLE22
ReplyDeleteNO, there are other differences though voltage is important.
Distribution networks are distinguished from transmission networks by their voltage level and topology. Lower voltages are used in distribution networks, as lower voltages require less clearance. Typically, lines up to 35 kV are considered part of the distribution network.
And there are other conditions that see yo that too such as PHASE, USAGE, VOLTAGE LEVEL, THICKNESS, CURRENT CONDUCTION LEVEL.
Yes...
ReplyDeleteTransmission lines are the big high-voltage lines that carry electricity over long distances, such as from a power station to a city, or from a grid to a city. They are generally high voltage and are placed on physically tall structures. Dominion Energy has about 6,600 miles of transmission lines
While
Distribution Lines
Distribution or sub-distribution lines are lower in voltage, and are the final stage in the delivery of electricity to end users. They are part of a network that typically includes medium-voltage power lines, substations, pole-mounted transformers, low-voltage distribution wiring and meters. Dominion Energy has nearly 57,000 miles of distribution lines, 900 substations, 566,000 transformers and 1.1 million utility poles.

Yes
ReplyDeleteTheir voltage level is the major in distinguishing between Transamission & Distribution. Transmission network conveys a huge amount of voltage e.g 330kv, 13kv over a long distance while a Distribution network conveys a low amount of voltage e.g 230/415v to the injection substation or final consumer.
No.Though it is major and most reasonable thing that first comes to mind.It is not the only factor.We still have to consider the topology of the line.
ReplyDeleteNo!..Voltage level is one the Paramount factor that distinguish transmission and distribution lines simply because all other factor depends on the voltage level...eg,the size of cable used,the distance,insulation used..e.tc..transmission and distribution system maybe merely be distinguished by factors like distance, size of conductors,insulators.substations (transformer rating) Not by voltage level...
ReplyDeleteYes, Transmission line can be distinguished merely by voltage level though there are some other factors like
ReplyDelete1. Phase differences
2. Current conditionion differences
3. Usage differences
4. Thickness of the condition also different them.

No!.
ReplyDeleteTransmission and distribution can be distinguish by
Voltage rate
Conductor size
Conductor material
Transformer rating
Line Support
Type and rating of protective device
Voltage regulating device etc
Taking a look at the aforemost mentioned elements, all this element clearly distinguish transmission from distribution.
The type of line (aluminum, steel core aluminum also know as ACSR etc.) U use ACSR for transmission because of it strength and it can stand long distance without lagging compare to ordinary aluminum for distribution. are different,
the line support (steel pole, steel tower, RCC pole, wooden pole) are different. You can use a wooden pole for distribution but not in transmission.

I'll say NO
ReplyDeleteBECAUSE,Transmission system voltages are typically from 69KV up to 765KV. Distribution systems typically operate in a voltage range of 4KV to 46KV.
