Ques:- Working principle of generators?
Asked In :-
Lumentum Operations,
Right Answer:
Generators work on the principle of electromagnetic induction, where mechanical energy is converted into electrical energy. When a conductor, such as a wire, moves through a magnetic field, it induces an electric current in the conductor. This process is governed by Faraday's law of electromagnetic induction.

Ques:- When will cause the negative sequence falut in electrical system?
Asked In :-
kinder morgan pipeline,
Right Answer:
A negative sequence fault in an electrical system occurs when there is an imbalance in the three-phase system, typically caused by a single-phase fault, such as a line-to-ground fault, or by unbalanced loads.

Ques:- Difference between earthing and grounding?
Asked In :-
Energytech Global,
Right Answer:
Earthing refers to the process of connecting the electrical system to the ground to ensure safety and prevent electric shock, while grounding is the connection of electrical equipment to the ground to stabilize voltage levels and provide a path for fault currents.

Ques:- How to calculate the size of window A.C. for 200 Sq. ft room?
Asked In :-
Right Answer:
To calculate the size of a window A.C. for a 200 sq. ft room, you typically need about 20 BTUs per square foot. Therefore, for a 200 sq. ft room, you would need approximately 4,000 BTUs (200 sq. ft x 20 BTUs/sq. ft = 4,000 BTUs).

Ques:- How to calculate the capacitor rating for improving power factor
Right Answer:
To calculate the capacitor rating for improving power factor, use the formula:
[ Q_c = P times (tan(phi_1) - tan(phi_2)) ]
Where:
- ( Q_c ) = reactive power of the capacitor in VAR (Volt-Ampere Reactive)
- ( P ) = active power in watts (W)
- ( phi_1 ) = initial power factor angle
- ( phi_2 ) = desired power factor angle
1. Determine the initial power factor (PF1) and the desired power factor (PF2).
2. Calculate the angles using ( phi = cos^{-1}(PF) ).
3. Substitute the values into the formula to find the required capacitor rating in VAR.
