A transformer is a 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
Works on the principle of electromagnetic induction
Used to step up or step down voltage levels in electrical circuits
Commonly used in power distribution systems
Transformer protection refers to the measures taken to prevent damage to transformers from faults or abnormal operating conditions.
Transformer protection devices include overcurrent relays, differential relays, and Buchholz relays.
Overcurrent relays protect against overloads and short circuits.
Differential relays compare the current entering and leaving the transformer to detect internal faults.
Buchholz relays detect g...
Electrical engineers work on a wide range of products including consumer electronics, power systems, communication devices, and more.
Consumer electronics such as smartphones, laptops, and TVs
Power systems including generators, transformers, and distribution systems
Communication devices like routers, modems, and cell phones
I applied via Naukri.com and was interviewed in Dec 2022. There were 3 interview rounds.
A 3-phase 4 wire system is a type of electrical system commonly used for power distribution.
Consists of three conductors carrying alternating current at the same frequency, with a fourth neutral conductor
Provides a more balanced and efficient power distribution compared to single-phase systems
Commonly used in industrial and commercial applications for higher power requirements
Example: Used in large factories, office bu
A characteristic of digital signal is that it is discrete and represented by binary numbers.
Digital signals are represented by discrete values
Digital signals are represented by binary numbers (0s and 1s)
Digital signals are less susceptible to noise compared to analog signals
Norton representation is preferred when the load impedance is known and fixed.
Norton representation is preferred when the load impedance is known and fixed, as it simplifies calculations.
Thevenin representation is preferred when the load impedance is unknown or variable.
Norton equivalent circuits are easier to analyze in terms of current flow and power calculations.
Thevenin equivalent circuits are easier to analyze in
