Jacobs Engineering Group Electrical & Instrumentation Engineer Interview Questions and Answers

To draw SFD and BMD for simply supported beam under UDL of 10KM/m, follow these steps:

• Calculate the reactions at the supports

• Draw the SFD by taking the upward forces as positive and starting from one end

• Draw the BMD by taking the positive moment as clockwise and starting from one end

• Mark the maximum values of SFD and BMD

• Check the equilibrium and compatibility of the beam

Types of faults in transmission lines

• Short circuit fault

• Open circuit fault

• Ground fault

• Transient fault

• Intermittent fault

Various types of protection used in generators, transformers, and grounding.

• Generator protection includes overcurrent, differential, and reverse power protection.

• Transformer protection includes overcurrent, differential, and Buchholz protection.

• Grounding protection includes earth fault protection and lightning protection.

• Other types of protection include overvoltage, underfrequency, and thermal protection.

• Each type of ...read more

There are two types of distribution systems: radial and network.

• Radial distribution system is a simple and common system where power flows in one direction from the source to the load.

• Network distribution system is a complex system where power flows in multiple directions through interconnected feeders and transformers.

• Radial system is suitable for areas with low power demand and less number of consumers.

• Network system...read more

I have experience in rating generators and transformers from my internship at NALCO Captive Power Plant.

• During my internship, I learned how to rate generators and transformers based on their capacity and efficiency.

• I gained hands-on experience in using instruments to measure the performance of generators and transformers.

• I also learned about the importance of regular maintenance and testing to ensure optimal performanc...read more
