Vindhya Telelinks Interview Questions and Answers for Experienced

Transmission lines (TL) use various conductors for efficient power transfer, including aluminum and copper types.

• Aluminum conductors are lightweight and have good conductivity, commonly used in overhead transmission lines.

• Copper conductors offer higher conductivity and are often used in underground cables and smaller applications.

• ACSR (Aluminum Conductor Steel Reinforced) combines aluminum and steel for strength a...read more

A 100 kVA transformer can handle a maximum load of 100 kVA, translating to approximately 80 kW for resistive loads.

• 1 kVA = 0.8 kW for resistive loads, so 100 kVA = 80 kW.

• The actual load depends on the power factor; for example, a power factor of 0.9 gives 90 kW.

• Transformers are rated in kVA because they can supply both active (kW) and reactive (kVAR) power.

• For example, a 100 kVA transformer can supply 100 kVA of t...read more

High Density Polyethylene pipe

• HDPE stands for High Density Polyethylene

• HDPE pipes are commonly used in water supply, drainage, and gas distribution systems

• They are known for their durability, flexibility, and resistance to corrosion

• HDPE pipes are lightweight and easy to install, making them a popular choice in construction projects

Hydro pressure testing of a line involves filling the line with water and pressurizing it to check for leaks or weaknesses.

• Fill the line with water to the required pressure level

• Monitor the pressure for a specified duration to ensure it remains stable

• Inspect the line for any leaks or weaknesses

• Release the pressure and drain the water from the line after testing

• Document the results and any necessary repairs or main...read more

A multi-purpose SCADA system can be created by designing a flexible and customizable interface with the ability to monitor and control various processes.

• Identify the different processes and systems that need to be monitored and controlled

• Design a user-friendly interface that allows for customization and flexibility

• Implement communication protocols to connect the SCADA system to various devices and sensors

• Include f...read more

S curve is a graphical representation of project progress over time.

• S curve shows the planned progress, actual progress, and forecasted progress of a project.

• It helps in tracking the project's performance and identifying any deviations from the plan.

• The curve is named after its S-shape, which is formed due to the slow start, rapid progress, and slow finish of a project.

• S curve is commonly used in construction, eng...read more
