Shyam Sel & Power ITI Fitter 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

Distribution refers to the delivery of electricity from high voltage transmission lines to individual customers. Transmission refers to the movement of electricity over long distances from power plants to substations.

• Distribution involves the delivery of electricity to individual customers through a network of power lines and transformers.

• Transmission involves the movement of electricity over long distances from power ...read more
