IRON TRIANGLE LIMITED (BACK BONE OFFICE) Senior Qa and Qc Civil Engineer Interview Questions and Answers

Bus bar schemes are different ways of connecting bus bars in power systems.

• Single bus bar scheme

• Double bus bar scheme

• Main and transfer bus bar scheme

• Ring bus bar scheme

• Breaker and a half scheme

• Mesh bus bar scheme

The equipment sequence for any line bay starts with the circuit breaker and ends with the transformer.

• The circuit breaker is the first equipment in the sequence.

• Next comes the isolator switch.

• After that, the earth switch is operated.

• Then the line disconnector is opened.

• Finally, the transformer is disconnected from the line.

• The sequence is reversed when the line bay is put back into service.

Stress is the force applied to a material, while strain is the resulting deformation or change in shape.

• Stress is the force applied per unit area on a material.

• Strain is the measure of deformation or change in shape of a material.

• Stress and strain are related by the material's modulus of elasticity.

• Example: When a rubber band is stretched (strain), the force applied to it is the stress.

Ductile materials exhibit large deformation before failure, while brittle materials fail suddenly with little deformation.

• Ductile materials have a gradual slope on the stress-strain curve, showing plastic deformation before fracture.

• Brittle materials have a steep slope on the stress-strain curve, showing little to no plastic deformation before fracture.

• Examples of ductile materials include steel and aluminum, while exa...read more

Design and Implementation of a Smart Home Automation System using IoT
