stepper motor

Stepper Motor working principle

Stepper motor is a special type of synchronous motor which is designed to rotate a specific number of degrees for every electric pulse received by its control unit. Typical steps are 7.5 or 15 degree per pulse. It is a motor that can rotate in both directions, move in precise angular increments, sustain a holding…

motor parts

Main Parts of Motor

Main Parts of Motor  Motor is an electrical machine that converts electrical energy into mechanical energy. Motors work through the principles of electromagnetism. If you run electricity through a wire, it creates a magnetic field. If you coil the wire around a rod and run electricity through the wire, it creates a magnetic field around…

ALTRENATOR

Difference between Alternator & Generator

Alternator Vs Generator Alternators and generators are two devices which generate electricity. Both alternators and generators convert mechanical energy into electrical energy. An alternator can be called a type of generator. Although both these devices serve the same function, they are quite different in every other aspect. An alternator is a charging system for cars…

Buchholz relay

Working of Buchholz Relay

In the field of electric power distribution and transmission, a Buchholz relay is a safety device mounted on some oil-filled power transformers and reactors, equipped with an external overhead oil reservoir called a “conservator”. Buchholz relay is a gas-actuated relay which is used for protection of oil filled transformers/reactors fitted with conservators against low oil…

types of insulator

What is Insulator? Types of Insulator?

Insulator A material or an object that does not easily allow heat, electricity, light, or sound to pass through it.  Air, cloth and rubber are good electrical insulators feathers and wool make good thermal insulators. The overhead line conductors are supported on the poles/ turns with the help of insulator to prevent the flow of…

types of generator

Types of Generator available in electrical field

Generator is the important power supply equipment to generated electricity. Without electricity, we cannot operated machinery, equipment, lighting, computer and others device for our living. For general power supply, power distributor normally used the high capacity of generator to supply the electricity to the consumer. It different size for backup power supply that used for…

sf6 circuit breaker

Sulphur Hexaflouride (SF6) Circuit Breakers

A circuit breaker in which the current carrying contacts operate in  sulfur hexafluoride or SF6 gas is known as SF6 circuit breaker. SF6 is a very good dielectric material which can resist high potentials.SF6 gas is used as the arc quenching medium Sulfur Hexafluoride (SF6) is an electro-negative gas and has a strong tendency to absorb free electrons. Whenever circuit breaker opens…

electric traction

What is Electric Traction systems

Electric Traction Systems The system which use electrical power for electric traction system i.e. for railways, trams, trolleys, etc. is called electrical traction. The track electrification refers to the type of source supply system that is used while powering the electric locomotive systems. It can be AC or DC or a composite supply.Selecting the type of…

converter

Difference between Converter and Inverter

Converters and inverters are electrical devices that convert current. Converters convert the voltage of an electric device, usually alternating current (AC) to direct current (DC). On the other hand, inverters convert direct current (DC) to alternating current (AC). Converter                             Inverter                                                                          What it is Electrical devices that convert the voltage from alternating current (AC)…

earthing

Types of Earthing & Electrical grounding systems

What is Earthing: The main reason for doing earthing in electrical network is for the safety. When all metallic parts in electrical equipment’s are grounded then if the insulation inside the equipment’s fails there are no dangerous voltages present in the equipment case. If the live wire touches the grounded case then the circuit is…
