An induction motor is an AC electric motor in which power is supplied to the rotor by electromagnetic induction.
Induction motors are widely used in various applications, including industrial machinery, household appliances, and transportation systems.
They work based on the principle of electromagnetic induction, where a rotating magnetic field is created by the stator winding, inducing current in the rotor.
The rotor of...
The stator is used in an induction motor to generate a rotating magnetic field.
The stator consists of a set of windings that are connected to an AC power source.
When the AC power is applied, the stator windings create a rotating magnetic field.
This rotating magnetic field induces currents in the rotor, which in turn creates a torque and causes the rotor to rotate.
The stator windings are typically made of copper or alum...
Transformers work on the principle of electromagnetic induction to transfer electrical energy between two or more circuits.
Transformers consist of two or more coils of wire called windings.
When an alternating current (AC) flows through the primary winding, it creates a changing magnetic field.
This changing magnetic field induces a voltage in the secondary winding, which is connected to the load.
The ratio of the number ...
There are two types of transformers according to voltage transfer: step-up transformers and step-down transformers.
Step-up transformers increase the voltage from the primary winding to the secondary winding.
Step-down transformers decrease the voltage from the primary winding to the secondary winding.
Step-up transformers are used in power transmission to increase voltage for long-distance transmission.
Step-down transfor...
A relay is an electrically operated switch that uses an electromagnet to mechanically control the switching action.
Relays are commonly used in electrical systems to control high power circuits with low power signals.
They consist of a coil, an armature, and one or more sets of contacts.
When the coil is energized, the armature is attracted and the contacts are closed or opened, depending on the relay type.
Relays can be u...
A contactor is an electrical device used for switching an electrical circuit on or off.
Contactor is used to control the flow of electricity in a circuit.
It consists of a coil, contacts, and an enclosure.
When the coil is energized, the contacts close and allow current to flow.
Contactor is commonly used in motor control applications.
Examples of contactor include magnetic contactor and air conditioning contactor.
MPCB and MCB are both circuit protection devices, but they differ in terms of their applications and trip characteristics.
MCB stands for Miniature Circuit Breaker, while MPCB stands for Motor Protection Circuit Breaker.
MCBs are primarily used for residential and commercial applications, while MPCBs are specifically designed for motor protection in industrial settings.
MCBs have a fixed trip current rating and are typica...
ELCB stands for Earth Leakage Circuit Breaker. It is a safety device used to protect electrical circuits from electric shock.
ELCB is designed to detect small leakage currents that may occur due to insulation failure or faulty wiring.
When an ELCB detects a leakage current, it quickly cuts off the power supply to prevent electric shock.
ELCBs are commonly used in homes, offices, and industries to ensure electrical safety.

There are several types of earthing used in electrical engineering.
The most common types of earthing are:
- TN-S system: separate neutral and protective earth
- TN-C system: combined neutral and protective earth
- TN-C-S system: combination of TN-S and TN-C systems
- TT system: separate earth for each electrical installation
- IT system: no direct connection to earth, relies on insulation monitoring
Other types include:
- TN-...
Neutral is a current-carrying conductor that completes an electrical circuit, while earth is a safety grounding conductor.
Neutral carries current back to the source in a balanced electrical system.
Earth is a safety measure to prevent electric shock and protect against electrical faults.
Neutral is typically connected to the center tap of a transformer, while earth is connected to the ground.
Neutral is part of the electr...

I applied via Walk-in and was interviewed in May 2022. There was 1 interview round.
The capacity of a furnace refers to its heating output, typically measured in BTUs or tons.
Furnace capacity is determined by the amount of heat it can produce.
It is usually measured in BTUs (British Thermal Units) or tons.
Higher capacity furnaces can produce more heat and are suitable for larger spaces.
For example, a furnace with a capacity of 80,000 BTUs can heat a larger area compared to one with a capacity of 40,000
Drive components in CCM department are the parts that enable the motor to function properly.
Drive components include motors, gears, belts, and pulleys.
They work together to transfer power from the motor to the machine.
The components must be properly sized and aligned to ensure efficient operation.
Examples of machines that use drive components include conveyor belts, pumps, and fans.

A step up transformer is a type of transformer that increases the voltage level from the input side to the output side.
Consists of more turns on the secondary coil than the primary coil
Used to increase voltage levels for long distance power transmission
Commonly found in power distribution systems and electrical grids
A distribution transformer is a device used to step down high voltage electricity to a lower voltage suitable for use in homes and businesses.
Converts high voltage electricity from power lines to lower voltage for distribution
Commonly used in electrical distribution systems
Helps reduce voltage for safe use in homes and businesses
Can be mounted on poles or placed on the ground
Examples: pole-mounted distribution transfor
An alternator is a device that converts mechanical energy into electrical energy in the form of alternating current.
An alternator is commonly used in vehicles to charge the battery and power the electrical system.
It consists of a rotor, stator, diode rectifier, and voltage regulator.
Alternators produce alternating current (AC) which is then converted to direct current (DC) for use in the vehicle.
They are more efficient...
A synonyms machine is a tool or software that helps find alternative words with similar meanings for a given word.
A synonyms machine can be a thesaurus or a feature in word processing software.
It helps writers and speakers find the right word to convey their message effectively.
Examples include online thesauruses like Thesaurus.com or built-in thesaurus in Microsoft Word.
A hysteresis motor is a type of synchronous motor that operates based on the hysteresis effect in magnetic materials.
Hysteresis motors have a rotor made of a magnetic material with high hysteresis, such as cobalt steel.
They do not require a separate DC excitation like other synchronous motors.
Hysteresis motors are known for their smooth operation and low noise levels.
They are commonly used in applications where precise...

Home load of a power plant is received through a distribution network.
Home load is received from the power plant through a distribution network.
The power plant generates electricity and sends it to a substation.
The substation then distributes the electricity to homes through power lines.
The distribution network ensures that the electricity reaches each home efficiently.
Examples of distribution networks include overhead
A blackout condition refers to a complete loss of electrical power in a specific area or across a larger region.
Blackouts can be caused by various factors such as equipment failure, severe weather conditions, or intentional power cuts.
During a blackout, all electrical devices and systems dependent on electricity cease to function.
Blackouts can last for a few seconds, minutes, hours, or even days depending on the cause ...
