A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
Consists of two coils of wire, known as primary and secondary coils
Primary coil receives electrical energy and creates a magnetic field
Magnetic field induces a voltage in the secondary coil, transferring energy
Used in power distribution, voltage regulation, and electrical isolation
Exampl...
Mutual induction is the process where a changing current in one coil induces a voltage in another coil.
Mutual induction occurs when two coils are placed close to each other and the magnetic field produced by one coil induces a voltage in the other coil.
The induced voltage in the second coil is directly proportional to the rate of change of current in the first coil.
This phenomenon is the basis for the operation of tran...
Flux is the flow of electric or magnetic field lines through a surface, while current is the flow of electric charge.
Flux is a measure of the flow of a physical property through a given area.
In electromagnetism, flux refers to the flow of electric or magnetic field lines through a surface.
Current is the flow of electric charge through a conductor.
Flux and current are related through Faraday's law of electromagnetic ind
I applied via Company Website and was interviewed before Jun 2022. There were 3 interview rounds.
DTR stands for Dead Time Recovery. It is a structure used in the oil and gas industry to separate gas and liquid phases.
DTR is typically made of steel or other corrosion-resistant materials.
The structure is designed to handle high pressure and temperature conditions.
Common materials used in the construction of DTR include carbon steel, stainless steel, and duplex stainless steel.
The choice of material depends on factor...
A Bucoz relay is a type of protective relay used in power systems to detect faults and isolate them to prevent damage.
Bucoz relay is a type of protective relay used in power systems.
It functions by detecting faults in the system and isolating them to prevent damage.
It helps in maintaining the stability and reliability of the power system.
Bucoz relay operates based on the principle of electromagnetic induction.
Examples ...
Pipe earthing of DTR involves using a metal pipe buried in the ground to provide a low-resistance path for fault currents.
Metal pipe is buried vertically in the ground near the DTR
The pipe is filled with alternate layers of charcoal and salt to improve conductivity
A copper wire is connected to the pipe and then to the DTR for grounding purposes

Questions related to torque, gearbox, torque limiter and coupling failure, yawing system bearing, and accumulator.
Torque is a measure of rotational force.
Gearbox works by transmitting power from the engine to the wheels.
Torque limiter failure can be caused by overloading or overheating.
Coupling failure can be caused by misalignment or excessive torque.
Yawing system bearing is a type of roller bearing used to support th...
7QC tools are a set of quality control tools used to identify and solve quality problems in manufacturing processes.
7QC tools include Pareto chart, cause-and-effect diagram, control chart, histogram, scatter diagram, flowchart, and check sheet.
They help in identifying and analyzing quality problems, determining root causes, and implementing corrective actions.
They are used to improve product quality, reduce defects, an...
PPAP and APQP are quality management systems used in manufacturing.
PPAP stands for Production Part Approval Process and is used to ensure that manufactured parts meet customer requirements.
APQP stands for Advanced Product Quality Planning and is used to plan and manage the design and development of new products.
Both systems are commonly used in the automotive industry but can be applied to other manufacturing industrie...
Pareto is a principle that states 80% of effects come from 20% of causes.
Also known as the 80/20 rule
Used in business to identify the most important factors
Can be applied to various fields such as economics, engineering, and social sciences
Example: 80% of a company's profits come from 20% of its customers
OEE can be calculated by multiplying Availability, Performance, and Quality percentages.
Calculate Availability by dividing Operating Time by Planned Production Time.
Calculate Performance by dividing Actual Production by Maximum Production.
Calculate Quality by dividing Good Units by Total Units Produced.
Multiply Availability, Performance, and Quality percentages to get OEE.
