The basic law governing transformers is the law of electromagnetic induction.
The law states that when the magnetic field around a conductor changes, an electromotive force (EMF) is induced in the conductor.
This EMF can cause a current to flow if the conductor forms a closed loop.
In a transformer, this principle is used to transfer electrical energy from one circuit to another through electromagnetic induction.
The prima...
Various losses in a transformer include copper losses, iron losses, and stray losses.
Copper losses occur due to resistance in the transformer windings.
Iron losses, also known as core losses, occur due to hysteresis and eddy currents in the transformer core.
Stray losses occur due to leakage flux and stray capacitance in the transformer.
Copper losses and iron losses are the major contributors to total losses in a transfo...
AC and DC are two types of electrical current. AC changes direction periodically while DC flows in one direction.
AC stands for Alternating Current and DC stands for Direct Current.
AC changes direction periodically, typically in a sinusoidal waveform.
DC flows in one direction only, maintaining a constant polarity.
AC is used for power transmission over long distances due to its ability to be easily converted to different...
An inverter is a device that converts DC power to AC power.
An inverter is commonly used in electrical systems to convert the direct current (DC) produced by sources such as batteries or solar panels into alternating current (AC) that can be used to power appliances and devices.
The basic working principle of an inverter involves the use of electronic components such as transistors to switch the DC input on and off rapid...
Solar panel installation requires several components including solar panels, inverters, mounting systems, wiring, and electrical protection devices.
Solar panels: These are the main components that convert sunlight into electricity.
Inverters: They convert the direct current (DC) produced by solar panels into alternating current (AC) that can be used in homes or fed into the grid.
Mounting systems: These are used to secur...

Miniature Circuit Breaker (MCB) - used in residential and commercial buildings
Molded Case Circuit Breaker (MCCB) - used in industrial applications
Air Circuit Breaker (ACB) - used for high voltage applications
Ground Fault Circuit Interrupter (GFCI) - used to protect against electrical shocks
Residual Current Circuit Breaker (RCCB) - used to detec...
I applied via Naukri.com and was interviewed in Nov 2020. There were 3 interview rounds.
The commissioning process of a PV solar plant involves testing, adjusting, and optimizing the system to ensure it is functioning properly.
Testing the electrical components and connections to ensure they are working correctly
Adjusting the system settings to maximize efficiency and output
Optimizing the performance of the solar panels to achieve the desired energy production
Checking for any potential issues or malfunction
Transformer types of testing include routine tests, type tests, and special tests to ensure proper functioning and safety.
Routine tests include insulation resistance, turns ratio, and polarity tests.
Type tests are conducted on a prototype to verify design parameters like temperature rise and short-circuit withstand.
Special tests may include impulse voltage, partial discharge, and noise level tests.
Testing ensures trans...

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
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
I applied via Naukri.com and was interviewed before Jun 2023. There were 3 interview rounds.
The gearbox oil grade is typically specified by the manufacturer based on the requirements of the gearbox.
Gearbox oil grade is determined by the viscosity and additives needed for proper lubrication.
Common gearbox oil grades include SAE 80, SAE 90, and SAE 140.
Consult the manufacturer's specifications or maintenance manual for the recommended gearbox oil grade.

A substation single-line diagram is a simplified representation of a power system showing the electrical connections and components.
It shows the electrical connections between various components in a substation, such as transformers, circuit breakers, and switches.
The diagram typically includes symbols to represent different types of equipment and their interconnections.
It helps engineers and operators understand the f...
A step-up transformer is used to increase the voltage in an electrical circuit.
Step-up transformers have more turns in the secondary coil than in the primary coil.
They work based on the principle of electromagnetic induction.
The primary coil is connected to a power source with a lower voltage, while the secondary coil is connected to the load.
The increased voltage in the secondary coil is proportional to the ratio of t...

The question is asking about the current of a unit.
The current of a unit refers to the amount of electric current flowing through a specific unit or device.
It is typically measured in amperes (A) or milliamperes (mA).
The current of a unit can vary depending on the specific device or circuit being discussed.
For example, the current of a unit could refer to the current flowing through a resistor, a transistor, or a motor...
Transformers are rated in KVA (kilovolt-amperes) to indicate their power capacity.
KVA stands for kilovolt-amperes, which is a unit of apparent power.
The KVA rating of a transformer indicates the maximum amount of power it can handle.
Transformers are available in various KVA ratings to suit different power requirements.
Higher KVA ratings indicate higher power capacity.
For example, a transformer with a 100 KVA rating can
Loop law, also known as Kirchhoff's voltage law, states that the sum of the voltages in any closed loop in a circuit is zero.
Loop law is a fundamental principle in electrical engineering.
It is also known as Kirchhoff's voltage law (KVL).
According to loop law, the algebraic sum of the potential differences (voltages) around any closed loop in a circuit is always zero.
It is based on the principle of conservation of energ...
