Multi-read content how to find load

I just came back to a basic post from one of our kind community members. What do you think?

One of the key elements in the design of a medium or low voltage electrical installation is to choose the right conductor for a given consumer. Therefore, in this article I will consider how the load is calculated and what kind of conductor you can use in different situations.

To calculate the load, we need to calculate the current flowing through the conductor. It can be calculated very easily thanks to the famous formula:

P = U * I * cosϕ, or:

P – capacity

U – network voltage

I present

cosϕ – power factor

suppose thatcosϕ = 1, so the formula becomesP = U * Iand we can deduce the formula of the current



For single-phase low-voltage electrical installations, the formula is:

single-phase-low-voltage-formula

For example, if we have powerful consumers1.45кWand240Vthe current that will flow will be:




single-phase-low-voltage-formula-2

There is also an easier way to calculate amps and that is when you create a constant. Because240Vconstant will be1000W / 240V = 4.17.

Once you have that constant, just multiply the consumer wattage by that constant and you’ll get amps.

I=1.45*4.17=6.05A


For low and medium voltage three-phase power systems, the formula is:

three-phase-low-middle-voltage-formula

with the same power 1.45kW and 400V the current will be:




three-phase-low-middle-voltage-formula-2



Here, the constant you need to multiply is:1000 / (400 * 3) = 1.45.

Or the formula for the current row would be:I=1.45*1.45=2.1A

This is how the loads should be calculated in an electrical installation and based on these you should choose the right conductor. The conductors are mainly made of copper and aluminum. They are also divided into voltage levels, protection levels and lying conductors.


Different types of low voltage conductors

Power-cable-low-voltage-1

Electric cables, Cu core, PVC insulation, PVC sheath used for the distribution and transport of energy in the construction of electrical distribution networks and installations have a nominal voltage of 1kV, frequency of 50 Hz. Suitable for fixed installation outdoors or indoors, in cable ducts, tunnels, pits and traction trenches.

Power-cable-low-voltage-2

Electrical cables, Cu conductors, PVC insulated, armored, PVC sheathed for permanent installation in networks and installations, designed for the transmission and distribution of electrical energy at nominal voltage 1kV and frequency 50 Hz.

Power-cable-low-voltage-3

Power cables, Al-core, PVC insulated, PVC sheath used for distribution and transmission of energy in the construction of distribution networks and installations with a nominal voltage of 1kV, frequency of 50 Hz. Suitable for a fixed installation outdoors or indoors, in cable ducts, tunnels, pits and traction trenches.

Flat-installation-conductor

Flat installation conductor, Cu wire, PVC insulation, PVC sheath for permanent installation in lighting networks and electrical installations.

conductor

Conductor in flexible Cu wire, insulated and PVC sheathed for the connection of electrical equipment to the network, users, equipment and mobile devices.


Different types of conductors for medium voltage

Power-cable-middle-voltage-1

Power cables, Cu conductors, XLPE insulated, PVC sheathed for fixed laying in networks and installations, designed for the transmission and distribution of electrical energy at nominal voltages of 6,10,20,30,35kV and a frequency 50 Hz. Suitable for fixed installation indoors, in cable ducts, tunnels and traction pits, on cable trays and racks, directly underground and outdoors under roofs.

Power-cable-middle-voltage-2

Electric cable, Al-core, PVC insulation, sheath, PVC sheath for fixed installation in networks and installations, designed for the transmission and distribution of electrical energy at nominal voltage 6kV and frequency 50 Hz.

Power-cable-middle-voltage-3

Power cables, Cu conductors with XLPE insulation and longitudinally sealed conductive sheath in the screen area, for the construction of municipal and local networks, for the connection of substations in the plant and project industry. Designed for the transmission and distribution of electrical energy at nominal voltages of 6, 10, 20, 30 kV.


Besides these conductors there are many others and that is why after calculating the load, before buying a conductor, ask the advisors in the store which is the right choice for you. Copper conductor is still better than aluminum conductor due to its better properties, but it is also more expensive.

When installing aluminum conductors, pay attention to two things:

  • Cut the conductor with a hand tool because if you cut it with a grinder for example, the lead may get dirty and you will not be able to place the cable lugs.
  • Do not bend the lead wire too much as it can easily break.

If the load is too much for one conductor, you can connect two conductors in parallel and thus the load will be distributed between them.


how to calculate the load

In conclusion, we can say that the calculation of the load and the choice of the right conductor for the electrical installation are very important because if you install the wrong conductor, it can cause a fire.

It’s good to go back to the basic concept articles, isn’t it? Give your thoughts in the comments below.

Popular questions about how to find load

how to find load?

Multiply the mass of the object by the gravitational acceleration of the earth (9.8 m/sec2), and the height in meters. This equation is the object at rest’s potential energy. Potential energy is measured in joules; this is the load force.

What is the formula for load?

Calculating an Electrical Load in a Simple Circuit

Let Power = Voltage * Current (P=VI). Let Current = Voltage/Resistance (I=V/R). Apply Kirchoff’s Second Law, that the sum of the voltages around a circuit is zero. Conclude that the load voltage around the simple circuit must be 9 volts.

How do you calculate load weight?

Calculating the Weight of a Load
  1. Step 1: Determine the Volume of the Load. Rectangle/Square: Volume = Length x Width x Height. …
  2. Step 2: Determine the Material You’ll Be Lifting. The table below can be used for approximate weight values of common loads and materials: …
  3. Step 3: Determine the Weight of Object.

How do you find the total load?

You can estimate the total running load by adding up the running wattages of all items to be powered. If the name plate show only amps and voltage the wattage can estimated by multiplying volts times amps to calculate watts. Amps times Volts equals Watts. The watts total divided by 1000 is kW.

How do you calculate kg load?

If given in grams, divide the mass by 1,000 to obtain a unit of kilograms. Ignore the length of the bar or the string from which the load is hanging.

How do you calculate load and effort?

In simple words and as per the formula, it’s the ratio of load and effort. The formula of the mechanical advantage(MA) of a lever is given as MA = load/effort. Another form of this ma formula is MA = Effort Arm/Load Arm = EA/LA.

How is kW load calculated?

We find the power in kilowatts P(kW) by dividing the power in watts P(W) by 1,000. Here’s the Formula for Converting Watts Into Kilowatts: P(kW) = P(W) / 1,000.
