Oil in transformers is used for cooling and insulation purposes.
Oil helps in dissipating heat generated in the transformer
It also provides insulation to prevent electrical breakdown
Mineral oil is commonly used in transformers for its dielectric properties
Water has poor dielectric properties and can cause electrical failures in transformers.
Water has poor dielectric properties, which can lead to electrical failures in transformers.
Water can cause corrosion and rusting of transformer components.
Water can also lead to insulation breakdown and reduced efficiency of the transformer.

Generator terminal voltage in a 210 MW unit is typically around 20-24 kV.
Generator terminal voltage is usually maintained within a specific range to ensure proper functioning of the unit
The voltage can vary based on the specific design and configuration of the generator
In a 210 MW unit, the terminal voltage is typically around 20-24 kV
Induction motors are commonly used in thermal power plants.
Induction motors are preferred due to their simplicity, reliability, and low cost.
They are used for driving pumps, fans, compressors, and other auxiliary equipment in thermal power plants.
Synchronous motors are also used for applications requiring precise speed control.
DC motors may be used in some specific cases where variable speed control is needed.
Major motors in a thermal power plant include boiler feed pump motor, forced draft fan motor, induced draft fan motor, and condensate extraction pump motor.
Boiler feed pump motor: used to pump feedwater into a boiler
Forced draft fan motor: used to supply air to the furnace for combustion
Induced draft fan motor: used to remove flue gases from the furnace
Condensate extraction pump motor: used to extract condensate from t

Power flows from one end to the other through a closed circuit, following the path of least resistance.
Power flows through conductive materials such as wires or cables.
It is generated at a power source, such as a generator or a battery.
The power source creates a potential difference, or voltage, which pushes the electrons to flow.
The electrons flow from the higher potential end to the lower potential end.
The flow of el...
When a fan rotates in the opposite direction, it reverses the airflow and can cause the fan to function improperly.
Reversing the direction of a fan can disrupt the intended airflow in a room.
In some cases, reversing the fan direction can lead to decreased cooling or heating efficiency.
Changing the fan direction can also affect the distribution of air in the room.
For ceiling fans, reversing the direction can change the ...
