Real Time Electrical Switchgear & Protection Interview Questions with Answers PDF 1. What are the main functions of control gear? 1. To provide a means of starting and stopping the motor and, at the same time, of limiting the starting current if required. 2. To give adequate protection to the motor under all conditions. 3. To allow speed changing when required. 4. To provide means of braking the motor when required. 5. To reverse the direction of rotation when required. Protection of the motor must be automatic, but the other operations may be arranged to be under the control of an operator, or may be partly or fully-automatic. 2. What provision must be made for short-circuit conditions in motor circuits? Since overload relays are not designed to operate and clear the circuit in the event of a short-circuit. Circuit-breaker or fuse protection of suficient breaking capacity to deal with any possible short-circuit that may occur must be provided. 3. What are the usual forms of overlo...

Real Time Strength of materials Interview Questions And Answers PDF 1. Define tensile stress and tensile strain. The stress induced in a body, when subjected to two equal and opposite pulls, as a result of which there is an increase in length, is known as tensile stress. The ratio of increase in length to th original length is known as tensile strain. 2. Define compressive stress and compressive strain. The stress induced in a body, when subjected to two equal and opposite pushes, as a result of which there is an decrease in length, is known as compressive stress. The ratio of increase in length to th original length is known as compressive strain. 3. Define shear stress and shear strain. The stress induced in a body, when subjected to two equal and opposite forces, which are acting tangentially across the resisting section as a result of which the body tends to shear off across the section is known as shear stress and corresponding strain is known as shear strain. 4. Sketch a composi...
