Rewinding a 72 slot 50 hp motor involves disassembling the motor, removing the old windings, and replacing them with new windings.
Disassemble the motor carefully to access the windings
Remove the old windings without damaging the core
Calculate the number of turns and wire gauge needed for the new windings
Wind the new coils carefully and evenly in the slots
Connect the windings properly and test the motor for functionalit
NO NC stands for Normally Open and Normally Closed. They refer to the state of a switch or relay when it is not activated.
NO (Normally Open) - the switch is open (off) when not activated
NC (Normally Closed) - the switch is closed (on) when not activated
Used in electrical circuits to control the flow of current
Commonly used in control panels, automation systems, and safety circuits
Earthing points are checked by using a multimeter to measure the resistance between the earthing point and the earth electrode.
Use a multimeter set to the resistance mode
Connect one probe to the earthing point and the other probe to the earth electrode
Check the resistance reading on the multimeter
A low resistance reading indicates a good earthing connection
Repeat the process for all earthing points in the system
Fan rewinding is the process of replacing the copper wire coils in the stator of a fan motor to restore its functionality.
Disconnect the fan from the power source before starting the rewinding process.
Remove the fan blades and outer casing to access the stator.
Carefully unwind the old copper wire coils from the stator and measure their length and gauge.
Select the appropriate gauge and length of copper wire for rewindin...
A contactor relay is an electrical device used to control a high-power circuit with a low-power signal.
Contactor relay consists of a coil, contacts, and an enclosure.
When the coil is energized, it creates a magnetic field that pulls the contacts together to close the circuit.
Contactor relays are commonly used in motor control circuits to start and stop motors.
They can also be used in lighting control, heating systems,

Technical & I.Q based Questions
The question is asking for the candidate's IQ level.
IQ level is a measure of a person's intelligence quotient.
It is typically assessed through standardized tests.
A high IQ level is often associated with problem-solving skills and quick learning ability.

TCL stands for Transaction Control Language in SQL, used to manage transactions in a database.
TCL commands include COMMIT, ROLLBACK, and SAVEPOINT.
COMMIT is used to save changes made in a transaction.
ROLLBACK is used to undo changes made in a transaction.
SAVEPOINT is used to set a point in a transaction to which you can later roll back.

Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.
Polymorphism is achieved through virtual functions and function overriding.
It allows for more flexibility and extensibility in code.
Example: A base class 'Shape' with virtual function 'draw', and derived classes 'Circle' and 'Square' that override 'draw'.
Different motions in a drone are achieved through varying the speed and direction of the propellers.
Changing the speed of the propellers controls the altitude of the drone.
Varying the speed of propellers on different sides of the drone allows it to move forward, backward, left, or right.
Adjusting the speed of the propellers diagonally creates rotational motion for turning.
Combining these motions enables the drone to pe
PID controller is a control loop feedback mechanism used in systems to control process variables.
PID stands for Proportional, Integral, Derivative.
Proportional term responds to the current error.
Integral term corrects the accumulated error over time.
Derivative term predicts future error based on current rate of change.
Tuning involves adjusting the three parameters (P, I, D) to achieve desired system response.
Example: I...
