Alliance India Site Engineer Interview Questions and Answers

SFD & BMD for a simply supported load

• SFD is a diagram that shows the variation of shear force along the length of a beam

• BMD is a diagram that shows the variation of bending moment along the length of a beam

• For a simply supported load, the SFD will be a straight line with a constant slope

• The BMD will be a parabolic curve with the maximum value at the center of the beam

• The SFD and BMD can be calculated using equations an

Precommissioning tests of transformers ensure proper functioning and safety before energizing.

• Visual inspection of transformer and its components

• Measurement of insulation resistance

• Measurement of winding resistance

• Verification of transformer ratio and polarity

• Verification of oil level and quality

• Testing of protective devices

• Verification of grounding

11kv & 33kv overhead power line distribution

• 11kv and 33kv are common voltage levels for overhead power lines

• Overhead power lines are used to distribute electricity from power stations to consumers

• The voltage level determines the distance the power can be transmitted and the size of the conductors needed

• Proper insulation and grounding is important for safety

• Maintenance and inspection of the lines is necessary to ensure
