I applied via Campus Placement and was interviewed before Jan 2020. There were 4 interview rounds.
Losses in transformers can be categorized as copper losses and iron losses.
Copper losses occur due to resistance in the windings and are also known as I^2R losses.
Iron losses occur due to hysteresis and eddy currents in the core.
Copper losses can be reduced by using larger conductors with lower resistance.
Iron losses can be minimized by using high-quality magnetic materials and proper core design.
Total losses in a tran...
Efficiency of a transformer is the ratio of output power to input power.
Efficiency is affected by factors such as core losses, winding resistance, and load impedance.
Efficiency can be improved by using high-quality materials and reducing losses.
Efficiency is typically expressed as a percentage and can range from 50% to 99%.
Efficiency is important in reducing energy waste and improving overall system performance.
Eddy current losses in transformers can be reduced by using laminated cores, increasing the core resistance, and minimizing the air gap.
Use laminated cores to reduce eddy current losses
Increase the core resistance by using high resistivity materials
Minimize the air gap between the core and windings
Use magnetic materials with low hysteresis losses
Reduce the frequency of the alternating current
Use thicker laminations to ...
High voltage is preferred for transmission of electrical power due to lower energy losses and reduced cost.
High voltage reduces energy losses during transmission
Reduced current flow at high voltage reduces the cost of transmission lines
High voltage allows for longer transmission distances
Step-up transformers increase voltage for transmission and step-down transformers decrease voltage for distribution
Examples of high v...
Humming noise is generated due to the vibration of magnetic domains in a magnetic material.
Magnetostriction is the property of magnetic materials to change their shape or dimensions when subjected to a magnetic field.
This change in shape causes the magnetic domains to vibrate, which in turn generates a humming noise.
The frequency of the humming noise is directly proportional to the frequency of the magnetic field.
Magne...
Electrical circuits involve the flow of electric current, while magnetic circuits involve the flow of magnetic flux.
Electrical circuits involve the use of conductors, insulators, and power sources to create a path for electric current to flow.
Magnetic circuits involve the use of magnetic materials, such as iron, to create a path for magnetic flux to flow.
Electrical circuits are used in a wide range of applications, inc...
Electrical appliances are devices that run on electricity to perform a specific task.
Examples include refrigerators, washing machines, televisions, air conditioners, and vacuum cleaners.
They are used in homes, offices, and industries for various purposes.
They make our lives easier and more convenient.
They require proper maintenance and care to ensure their longevity and safety.
Transformer tests are conducted to ensure the transformer's performance and reliability.
Transformer turns ratio test checks the turns ratio between primary and secondary windings.
Insulation resistance test measures the insulation resistance between windings and ground.
Transformer winding resistance test measures the resistance of the windings.
Transformer polarity test checks the polarity of the windings.
