- Q1. What type of dampings are there in case of vibration.
- Ans.
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...

- Q1. Why nitrogen gas uses in accumulator?
- Ans.
Nitrogen gas is used in accumulators due to its inert properties and ability to maintain pressure for extended periods of time.
Nitrogen gas is inert, meaning it does not react with other substances, making it ideal for maintaining pressure without causing corrosion or contamination.
It is also non-flammable, which reduces the risk of fire hazards in accumulator systems.
Nitrogen gas has a stable temperature range, allowi...
- Q2. Why accumulator is used in WTG
- Ans.
Accumulator is used in WTG to store excess energy generated by the wind turbine for later use.
Accumulator helps in smoothing out the power output from the wind turbine.
It allows for energy storage when the demand is low and release of stored energy when the demand is high.
Accumulators can also help in providing backup power during periods of low wind.
Examples of accumulators used in WTG include batteries, flywheels, an

- Q1. Draw Induction Motor equivalent ckt.
- Ans.
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...
- Q2. Draw B-H curve
- Ans.
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.
