Odisha Power Generation Corporation Engineer Interview Questions and Answers

Earthquake effects on structures and design process, including Richter scale and other scales.

• Earthquakes can cause various effects on structures, such as shaking, ground rupture, and liquefaction.

• The design process for structures takes into account the potential seismic forces and aims to ensure safety.

• The Richter scale is a logarithmic scale used to measure the magnitude of an earthquake.

• Other scales used for earthqu...read more

There are several types of dampings in case of vibration, including viscous damping, hysteretic damping, and structural damping.

• Viscous damping: It occurs when a fluid or viscous material is used to dissipate energy and reduce vibration.

• Hysteretic damping: It is caused by the internal friction within a material, which converts mechanical energy into heat.

• Structural damping: It is inherent in the structure itself and is...read more

Induction Motor equivalent circuit consists of stator and rotor circuits with mutual induction.

• The stator circuit includes three-phase winding and a power source.

• The rotor circuit includes rotor winding and a short-circuited conductor.

• The mutual induction between stator and rotor circuits causes the rotor to rotate.

• The equivalent circuit can be represented using a circuit diagram with resistances, inductances, and mutu...read more

B-H curve is a graph that shows the relationship between magnetic field strength and magnetic flux density.

• B-H curve is used to characterize the magnetic properties of a material.

• It is a plot of magnetic flux density (B) versus magnetic field strength (H).

• The slope of the curve at any point is the permeability of the material at that point.

• The curve can be used to determine the saturation point of a material.

• Examples o...read more
