A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Transformers are used to increase or decrease the voltage of an alternating current (AC) power supply.
They consist of two coils of wire, called the primary and secondary, wrapped around a magnetic core.
When an AC current flows through the primary coil, it creates a magnetic field that in...
Earthing is the process of connecting electrical equipment to the earth to prevent electric shock.
There are several types of earthing, including plate earthing, rod earthing, pipe earthing, and strip earthing.
Plate earthing involves burying a copper plate in the earth and connecting it to the electrical equipment.
Rod earthing involves driving a copper rod into the earth and connecting it to the electrical equipment.
Pip...
Circuit breakers are of different types such as thermal, magnetic, hydraulic-magnetic, and residual current devices.
Thermal circuit breakers use a bimetallic strip to trip the breaker when it gets too hot.
Magnetic circuit breakers use an electromagnet to trip the breaker when it detects an overload.
Hydraulic-magnetic circuit breakers combine the features of both thermal and magnetic circuit breakers.
Residual current de...
Star delta starter is an electrical motor starting mechanism that reduces the starting current and torque.
Used for starting high power motors
Consists of three contactors and a timer
Initially starts the motor in star configuration and then switches to delta configuration
Reduces starting current and torque
Commonly used in industrial applications
Buchholz relay is a protective device used in oil-filled transformers to detect and prevent faults.
It is a type of gas actuated relay
It is installed in the oil-filled transformer tank
It detects the presence of gas or air bubbles in the oil
It trips the transformer if a fault is detected
It helps to prevent major damage to the transformer

Fe500 is a type of high-strength reinforcement steel used in construction.
Fe500 stands for 'Fe' meaning iron and '500' representing the minimum yield strength of the steel in megapascals (MPa).
It is commonly used in construction for its high strength and durability.
Fe500 steel bars are used in reinforced concrete structures such as buildings, bridges, and highways.
It is also known as TMT (Thermo-Mechanically Treated) s...

To draw SFD and BMD for simply supported beam under UDL of 10KM/m, follow these steps:
Calculate the reactions at the supports
Draw the SFD by taking the upward forces as positive and starting from one end
Draw the BMD by taking the positive moment as clockwise and starting from one end
Mark the maximum values of SFD and BMD
Check the equilibrium and compatibility of the beam

The grade of concrete refers to its strength and is classified based on its compressive strength.
Concrete grades range from M5 to M100, with M representing mix and the number representing the compressive strength in megapascals (MPa).
The most commonly used grades of concrete are M20, M25, and M30.
Higher grade concrete is used for structures that require greater strength, such as bridges and high-rise buildings.
The grad...
