Adani Solar Electrical Technician Interview Questions and Answers

Q1. Basic law of governing transformer
Ans. 
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...read more

Q2. What are various losses in transformer
Ans. 
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...read more

Q3. Difference between AC and DC
Ans. 
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...read more

Q4. What is mean by inverter and its basic working
Ans. 
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...read more

Q5. What all component are required in solar panel installation and brief them
Ans. 
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...read more
