Electric line

Electric Line: An electric line is a cord, conductor, or other equipment used to transmit, transform, or supply electricity at a voltage greater than extra-low. On the other hand, an electric line does not include a wire or conductor directly used to convert electricity into another form of energy; or A wire or conductor within a building’s internal structure.

What Are Electric Lines?

However, the term “electric line” can relate to:

  • Electrical installation

  • Overhead lines that provide power to a railway

  • The Metra Electric Line is a commuter rail line that serves the Chicago area.

  • Wireline (cabling): Generally, a cabling technology is used in oil well exploration and completions to send a current to downhole logging tools.

Examples Of Non-Electric Lines Include:

  • A cord connects an air conditioner, computer, lamp, television, or toaster to an electrical supply.

  • A building’s power or lighting circuit.

Voltage On Power Lines:

However, most line-to-line voltages in the United States are standardized between 110 and 120 volts. Thus, the amount of power that enters a home or building may vary slightly. Most utility companies strive to provide at least 114 volts. Further, up to 126 volts for their electrical systems.

The Highest Voltage Transmission Line:

However, in Madhya Pradesh, Binah is home to the world’s highest 1200 kV UHVAC substation. Further, a single loop 1,200 kV line should carry 6,000 to 8,000 MW of power. As a result, higher performance per meter is prioritized over 400 kV and 800 kV transmission systems.

Power Lines Transport Voltage:

In the United States, the voltage on power lines ranges between 110 and 120 volts. Furthermore, in other countries, the voltage can reach 220 volts. Thus, the line transports energy to its final destination.

:white_check_mark: Summary:

Basically, it was the world’s first commercially used power line. As a result, it operated at 1,150 kV, the world’s highest transmission line voltage.

Electric Field Line:

Generally, electric field lines are an excellent way to depict electric fields. However, Michael Faraday was the first to introduce them. At one point, the field line is drawn tangentially to the network. However, the tangent of the electric field line corresponds to the direction of the electric field at any point.

However, when a unit charge or point charge enters the electric field of another charged particle, it feels a force. Thus, the imaginary lines represent the direction of this force. Thus, these fictitious lines are known as electric lines of force. Hence, electric force lines are also known as electric field lines.

Electric Flux:

The term flux derives from the Latin Fluxus, which means flow. Firstly, flux is anything that moves continuously from one point to another. Similarly, electric flux refers to the flow of electric lines of force from one point to another. However, electric flux is simply the flow of electric lines of force or electric field lines.

What Do The Electrical Terms Line And Load mean?

Generally, the line and load are the electrical connections that allow electrical devices to enter. Its exits in your electrical system’s schematic. All of this is relative because the charging cable for one device is frequently the line cable for the next device in the circuit.

What Causes Magnetic Fields In Power Lines?

Firstly, electric charges create electric fields. While electric current flowing through electrical cables or devices generates magnetic fields. Low-frequency TRAs can thus be found near power sources such as power lines.

Is there a federal standard for electromagnetic fields emitted by power lines? In the United States, however, no federal regulations limit electromagnetic fields from power lines and other similar sources. Further, some states have established priority standards under power lines because of the risk of electric shock.

What Exactly Are Electrical Lines Of Force?

Power transmission lines: They understand that a force acts on a single or point charge when placed in the electric field of another charged particle. As a result, the force’s direction can be represented by imaginary lines. Thus, these fictitious lines are known as lines of force.

Why Don’t Two Electric Lines Of Force Ever Cross?

Because if they intersect, there are two tangents in a point. And thus, two directions of the electric field in a point that is not possible. As a result, the electric field’s two lines of force never intersect.

Examples Of Electric force:

However, there are the following some examples of electric force:

  • The charge in a light bulb.

  • Circuits of electricity

  • When rubbed by a dryer, static friction occurs between the cloth.

  • The sensation of being shocked after touching a doorknob

:white_check_mark: Summary:

Firstly, electric field lines are a great way to visualize electric fields. Michael Faraday was the first to introduce them. On the other hand, a field line is drawn tangentially to the net at a point. Thus, at any point, the tangent to the electric field line corresponds to the direction of the electric field.

What Exactly Is Overhead Voltage?

All bare or insulated overhead electrical conductors with a voltage greater than 600 volts are considered overhead power lines, typically measured between conductors or a conductor and the ground. Furthermore, de-energized, grounded, or capped conductors are omitted. Thus, a rigid metal conduit or flexible armored conduit.

What Exactly Is A Power Transmission Line?

Firstly, transmission lines in an electric power system transport electric energy from one location to another. Secondly, they can carry alternating, direct, or a combination of the two. Overhead or underground lines can also carry electric current.

Power Line:

Generally, the apparatus provides a power supply with at least two input terminals. Thus, a first input terminal connected to the conductive body is included. Though, a second input terminal is connected to the power line. However, a power line is a set of conductors transmitting and distributing electrical energy.

Dangers Of Living Near Power Lines:

Living near power lines endangers your health and is undoubtedly the cause of leukemia, cancer, and other reported symptoms.

High Tension Power Line:

The power line has an operating voltage of 33 kV, so the operating voltage of this line is between 11 kV and 33 kV. If it is higher than 33 kV, it is referred to as an EHV line. Because the high voltage lines are not directly connected to the load, there are few faults. Larger structures with longer insulating wires are needed for higher voltage transmission.

:white_check_mark: Summary:

The voltage of the power lines determines the safe working distance. Always keep at least 10 feet away from overhead power lines. And up to 10 feet if the voltage to ground exceeds 50 kilovolts (50,000 volts). The greater the voltage, the greater the distance between the lines and the workers.

Disasters On High Voltage Transmission Lines:

Maintain high voltage areas that are dry and weatherproof. Access to high-voltage areas should be restricted. And only adequately trained individuals should operate high-voltage equipment. As needed, multiple levels of restricted or restricted access should be used.

Most Faulty Part Of A High Voltage System:

Fairchild’s article on High and High Voltage Safety for CERN’s School of Particle Accelerators is as follows: The person using the system is the most prone to error. High voltage protection systems, on the other hand, must be dependable.

Relationship Between High Voltage And Radiation Safety:

Generally, more information is available on the Radiation Protection page (in progress). However, electrical disturbances can be caused by electric fields associated with high voltages. And free charge movement through a dielectric medium (usually air). In contrast to an electric arc, the charge does not have to terminate on the second conductive surface.

What can I do if a high-voltage cable comes into contact with me?

To limit the current in the circuit:

  1. Use fuses, circuit breakers, resistors, and ground circuit interrupters (GCFIs).

  2. Inspect power lines regularly for holes, breaks, cuts, or structural changes that may indicate wear.

  3. Replace any damaged devices right away.

How Does Power Get To A Transmission Line?

Electrical energy is “boosted” to several thousand volts in the power plant by a transformer and then transferred to the overhead line. Thus, transformers reduce the current to a lower voltage in many transmission network substations. And then connect it to the distribution lines. On the other hand, distribution lines transport electricity to farms, homes, and businesses.

  3. Electric lines of force cannot ever intersect.

Q2: Which is the load, and which is the line?

Firstly, the incoming source power is connected to the line side of an outlet. And the load side is where the device’s power exits (or electrical box) or follows the circuit.

Q3: What do magnetic field lines go by?

Magnetic field lines are, in general, imaginary lines. Magnetic field lines, on the other hand, are a visual tool for representing magnetic fields. However, they describe the magnetic force direction on a north monopole at any given position. The line density indicates the magnitude of the field.

Q4: What exactly is a unit charge?

However, a unit charge is one Coulomb of charge, the standard unit of charge. As a result, one Coulomb of charge equals electrons or protons. Coulombs are equal to one electron. It is the charge transported by a one-ampere steady current in one second.

Q5: What is the SI unit for the magnetic field?

Teslas B and H truly represent the magnetic field. Amperes per meter is the unit of measurement for H. B, on the other hand, is measured in Teslas or Newtons per meter per ampere.

Q6: What is the voltage in residential power lines?

Firstly, residential electric service is available at two voltage levels: 120 and 240 volts. Secondly, the actual voltage in the house may vary because these are nominal values. 240-volt electric service is frequently referred to as “220.”

Q7: Are power lines alternating current (AC) or direct current (DC)?

Most utility support power plants generate alternating current (AC), which is used by the majority of electrical loads. As a result, the vast majority of power transmission lines on the planet are alternating currents.

Q8: Do power lines have a neutral?

The MGN, or multi-grounded neutral line, runs directly underneath the transmission lines. The transmission lines are linked to a grounded neutral conductor, which serves as a return path for electricity. The ground wire or grounding [conductor] (https://howtodiscuss.com/t/train-conductor/100844) is the multi-grounded neutral line.

Q9: Can you get your hands on a power line?

Because power lines are insulated, they are safe to touch. Thus, a common misconception about power lines that many people hold. Power lines are not insulated, and you should avoid contacting them at all costs. If you come into contact with power lines, you could get electrocuted.

Q10: What exactly is a 69 kV line?

SRP’s neighborhood electrical system is supported by a transmission network of 69kV power lines. These power lines connect local substations, providing redundancy and reliability to the system. The 69kV is converted to 12kV at the substations. It feeds into homes, schools, and businesses.

Q11: Why are power lines not insulated?

Transmission lines do not have an insulating sheath because they carry large amounts of electricity at very high voltage. However, they are insulated by the air around them. As a result, nothing should come close enough to the lines to cause an electric arc.

Q12: What is the distinction between a magnetic field and a magnetic field line?

A magnetic field is depicted as a series of lines circling a magnet. The north pole’s routes in a magnetic field are known as magnetic lines of force or magnetic field lines.

Q13: A power line has how many amps?

Depending on the weather, the line can carry 500-1000 amps. Lower resistance is aided by cooler temperatures, clouds, and wind. As a result, the voltage can cause more electrons (amperage) to flow through the conductor matrix. Usually took the photo during the power line installation.

Q14: Transmission lines are made of what material?

The primary conductor materials used in electrical power systems are copper, aluminum, and steel. Other conductors, such as silver and gold, are better electrical conductors. However, the high cost of these materials prevents them from being widely used.

Q15: Who was the first to discover electric field lines?

Michael Faraday, a 19th-century physicist, was the first to propose the concept of an electric field. Faraday believed that the pattern of lines that characterizes the electric field represents an invisible reality.

Q16: What are the different types of earthing?

There are three types of the earth:

  • Pipe earthing

  • Plate earthing

  • Strip earthing

Q17: What is the voltage between neutral and earth?

In an alternating current system, neutral and earth should ideally be at the same potential. It means that the voltage measured between the neutral and the earth should be zero.

Q18: Why is it possible for a bird to perch on a power line?

Because birds on a wire do not come into contact with the ground, electricity remains in the power line. However, if a bird comes into contact with a grounded power line, equipment, or other metal. As a result, electricity can travel to the ground and shock the bird.

Q19: What is the thickness of transmission lines?

They are typically one or two inches in diameter. A shield wire is a smaller wire located at the top of the structure. The shield wire aims to protect the power line from lightning strikes. Additionally, fiber optic communication cables may be present.

Q20: Is it true that all power lines are high voltage?

Some power lines transport electricity at high voltages. At the same time, others transport electricity at low voltages. These lower voltages power everything in your house.


An electric line of force is an imaginary continuous line or curve drawn in an electric field that, when tangent to, gives the direction of the electric force at that point. A line of force’s direction is the direction a small free positive charge will move along the line. As a result, it is always directed from positive to negative charge. Electric force lines contract longitudinally, one of its most essential properties. They spread laterally. Two electric lines of force cannot cross one another. Two electric force lines moving in the same direction repel each other. Two electric lines of force moving in opposite directions are attracted to each other.
