Tata Power Solar Civil Site Engineer Interview Questions and Answers

Pulling sub-stesan experience

• Sub-stesan refers to a subset of a larger system or process

• Pulling sub-stesan experience means extracting relevant information from a smaller part of a system

• This experience can be useful in identifying and solving specific quality issues

• Examples include analyzing data from a specific production line or testing a particular component of a product

Concrete grades are classifications that indicate the strength of the concrete mix used in construction.

• Concrete grades are denoted by the letter 'M' followed by a number, such as M20, M30, etc.

• The number after 'M' represents the compressive strength of concrete in N/mm^2 after 28 days of curing.

• Higher grade numbers indicate higher strength concrete, suitable for different types of construction projects.

• For example, M2...read more

Concrete strength typically reaches about 70-80% of its final strength after 7 days.

• Concrete strength gain after 7 days is usually around 70-80% of its final strength

• Factors such as mix design, curing conditions, and type of cement can affect the rate of strength gain

• For example, high early strength concrete may reach higher percentages of its final strength after 7 days compared to normal concrete

Non destructive testing of concrete is a method used to evaluate the properties of concrete without causing damage.

• Methods include ultrasonic testing, rebound hammer, and ground penetrating radar.

• These tests help assess the strength, durability, and quality of concrete structures.

• Non destructive testing is essential for ensuring the safety and longevity of buildings and infrastructure.

• Examples of non destructive testin...read more

Transportation of concrete involves mixing, loading, and delivering the concrete to the construction site.

• Concrete is mixed at a batching plant using cement, sand, gravel, and water.

• The mixed concrete is then loaded into transit mixers or concrete trucks for transportation.

• Transit mixers rotate to prevent the concrete from setting during transportation.

• Concrete pumps can also be used to transport concrete to hard-to-re

Admixtures are used in ready mixed concrete to improve workability, durability, and strength.

• Admixtures help in reducing water content while maintaining workability.

• They enhance the durability of concrete by reducing permeability and increasing resistance to chemicals.

• Admixtures can also accelerate or retard the setting time of concrete.

• Examples of admixtures include water reducers, accelerators, retarders, and air-ent

A 1 gigawatt required pallet is a pallet that can handle the weight and power requirements of a 1 gigawatt load.

• A 1 gigawatt required pallet needs to be able to support the weight of a 1 gigawatt load.

• It should have a strong and sturdy construction to prevent any damage or collapse.

• The pallet should be designed to handle the power requirements of a 1 gigawatt load, ensuring proper electrical connections and insulation.

• ...read more

Blocking diodes are used in junction boxes to prevent reverse current flow and protect electrical components.

• Blocking diodes are used to prevent reverse current flow in electrical circuits.

• They protect electrical components from damage caused by reverse voltage.

• Blocking diodes are commonly used in junction boxes to ensure proper current flow.

• They are also used in solar panels to prevent power loss due to reverse curren...read more

If module temperature increases, it can lead to reduced efficiency, increased stress on components, and potential failure.

• Increased temperature can cause a decrease in the efficiency of the module.

• Higher temperatures can lead to increased stress on components, potentially reducing their lifespan.

• Excessive heat can cause thermal expansion and contraction, which may result in mechanical failure.

• Increased temperature can ...read more
