Bus bar schemes are different ways of connecting bus bars in power systems.
Single bus bar scheme
Double bus bar scheme
Main and transfer bus bar scheme

The equipment sequence for any line bay starts with the circuit breaker and ends with the transformer.
The circuit breaker is the first equipment in the sequence.
Next comes the isolator switch.
After that, the earth switch is operated.
Then the line disconnector is opened.
Finally, the transformer is disconnected from the line.
The sequence is reversed when the line bay is put back into service.

The manufacturing of cement involves chemical reactions with water, resulting in the durability of concrete.
Cement is made by heating limestone, clay, and other materials in a kiln
The chemical reaction between cement and water, known as hydration, results in the hardening of concrete
The durability of concrete depends on factors such as the water-cement ratio, curing time, and quality of materials used
Calculate deflection at free end of cantilever beam with point load at end
Use the formula: δ = (PL³)/(3EI)
P is the point load at the end
L is the length of the cantilever beam
E is the modulus of elasticity of the beam material
I is the moment of inertia of the beam's cross-sectional area
Example: A steel cantilever beam with a length of 2 meters and a point load of 500 N at the end has a deflection of 0.104 mm
Camber is the slope provided to the road surface to drain off rainwater. It is achieved by raising the center of the road surface.
Camber is the curvature provided to the road surface to ensure proper drainage of rainwater.
It is achieved by raising the center of the road surface.
The amount of camber depends on the width of the road and the expected rainfall.
The steps for the construction of a road include surveying, cle...
Admixtures are chemicals added to concrete to enhance its properties. They affect the workability, strength, and durability of concrete.
Admixtures are added to concrete to improve its quality and performance.
They can affect the setting time, workability, strength, and durability of concrete.
Examples of admixtures include water reducers, accelerators, retarders, air-entraining agents, and superplasticizers.
Hoop stress is the stress exerted circumferentially in a cylindrical or spherical object. Reinforcement in a dome can be provided by using steel bars or mesh.
Hoop stress is caused by the pressure inside the object and is calculated using the formula P*r/t, where P is the pressure, r is the radius, and t is the thickness of the object.
In a dome, reinforcement can be provided by using steel bars or mesh that are placed i...
Estimation and costing involves calculating the expenses of a project. No. of bricks required in 1 m3 of brickwork depends on the size of the bricks. There are various types of contracts in construction.

Load cases in STAAD are used for qualification purposes to ensure structural safety.
Load cases are combinations of loads that a structure may experience during its lifetime.
Qualification load cases are used to ensure that the structure can withstand the maximum expected loads.
Examples of load cases include dead load, live load, wind load, seismic load, and temperature load.
Each load case is analyzed separately to deter...
Stiffness value refers to the resistance of an object to deformation under an applied force.
Stiffness is a measure of how much force is required to deform an object.
It is often used in engineering to describe the rigidity of a material or structure.
Stiffness can be calculated using Hooke's Law, which states that the force required to deform an object is proportional to the displacement.
For example, a steel beam is stif...
Level in survey refers to the height or elevation of a point relative to a reference point.
Level is a measurement of height or elevation in surveying.
It is used to determine the difference in elevation between two points.
A level instrument, such as a level rod or laser level, is used to take measurements.
Leveling is important in construction, engineering, and land surveying.
Examples of level surveys include topographic...
Cement mortar strength refers to the ability of the mixture to resist compression and tension forces.
Cement mortar strength is measured in terms of compressive strength and tensile strength.
The compressive strength of cement mortar is determined by subjecting a cube of the mixture to a compressive load until it fails.
The tensile strength of cement mortar is determined by subjecting a prismatic specimen of the mixture t...
