1. Project OverviewThis project involves the construction of the new Jakarta–Bandung High-Speed Railway, with a mainline length of 142.3 km, including 76.79 km of bridges (54.5%), 16.47 km of tunnels (11.69%), and 47.64 km of embankments (33.81%). Four stations—Halim, Karawang, Padalarang, and Tegal Luar—have been constructed. The Jakarta–Bandung HSR mainline is 142.3 km long, designed for a maximum speed of 350 km/h, with a double-track spacing of 4.6 m, including approximately 83.6 km of balla

UHV (Ultra-High Voltage) substations are a critical component of power systems. To meet the fundamental requirements of power systems, the associated transmission lines must remain in good operational condition. During the operation of UHV substations, it is essential to properly implement the inter-bay jumper installation and construction techniques between structural frames to ensure rational interconnection among the frames, thereby fulfilling the basic operational needs of UHV substations an

Dc generator definitionA DC generator is defined as an electrical device that converts mechanical energy into direct current (DC) electricity. It works according to the principle of electromagnetic induction, when a conductor passes through a magnetic field, it creates a potential difference in the conductor, which, if connected to a closed circuit, causes a current to flow.Structure of DC generatorYokeThe yoke is usually made of cast iron or cast steel, depending on the size and weight of the g

Definition of alternatorAn alternator is defined as an alternator that uses a rotating field and a fixed armature to convert mechanical energy into electrical energy.Components of an alternatorThe alternator consists of two main parts: the rotor (rotating) and the stator (stationary).The construction of alternatorThe structure includes an exciting pole on the rotor and an armature conductor on the stator, which senses a three-phase voltage.Type of rotorConvex pole type (for low speed)The word "p

Synchronous Motor DefinitionA synchronous motor is defined as a motor that runs at synchronous speed, determined by supply frequency and the number of poles.Where, Ns = synchronous speed, f = supply frequency and p = number of poles.Stator ComponentsStator FrameThe stator frame is the outer part of the motor, made from cast iron. It protects all the internal components of the motor. Stator CoreThe stator core is made from thin silicon laminations with an insulating surface coating. This reduces

Three phase induction motor definitionThe three-phase induction motor is defined as a type of electric motor that is most widely used in industry due to its efficient power delivery and simple structure.Main component The motor consists of a stationary component called a stator and a rotating component called a rotor. Three-phase asynchronous motor statorStator frameIt is the exterior of the three-phase induction motor. Its main function is to support the stator core and the excitation winding.

What is the Cyclotron Basic Construction?Cyclotron definitionA Cyclotron is defined as a device that uses magnetic and alternating electric fields to accelerate charged particles.Basic structureThe Cyclotron consists of an electromagnet, two D-shaped boxes, and a high-frequency AC voltage source.Working principleCyclotrons accelerate particles by moving them along circular paths in vertical magnetic and alternating electric fields.Particle accelerationBecause of the AC voltage, the particles gai

Bridge circuit is nothing but the electrical circuit configuration which is used to measure unknown values of the resistance, impedance, induction, and capacitance. Many bridges like Wheatstone bridge, Maxwell Bridge, Kelvin Bridge, and many more are very useful to measure quantities with accuracy and working on the same principle. Here is a brief description of functioning of some of the bridges given below:Wheatstone BridgeA Wheatstone bridge is an electrical circuit developed by Charles Wheat

Before understanding the basic working principle of Cyclotron it is necessary to understand force on a moving charged particle in a magnetic field and also motion of the charged particle in the magnetic field.Force on a Moving Charged Particle in a Magnetic FieldWhen a current carrying conductor of length L metre with current I ampere placed perpendicularly in a magnetic field of flux density B Weber per metre square, then the force rather to say magnetic force acting on the conductor would beNo
