- Q1. AutoCAD 2D Tools : Trim, Fillet, Blocks
- Q2. What is AI/AO and DI/DO (Analog Input/Output and Digital Input/Output)
- Ans.
AI/AO and DI/DO stand for Analog Input/Output and Digital Input/Output, respectively.
AI/AO refers to signals that are continuous and can have infinite values, like voltage or current.
DI/DO refers to signals that are discrete and can only have two states, like on/off or high/low.
Examples of AI/AO devices include temperature sensors and pressure transducers.
Examples of DI/DO devices include push buttons and relays.
- Q3. What is Ladder Logic?
- Ans.
Ladder Logic is a programming language used in industrial control systems to create logic circuits for controlling machinery and processes.
Ladder Logic is based on relay logic and uses graphical symbols to represent logic functions.
It consists of rungs, which are horizontal lines where input and output devices are connected using logic symbols.
Ladder Logic is commonly used in Programmable Logic Controllers (PLCs) for a...

- Q1. Different types of faults
- Ans.
Different types of faults in electrical engineering include short circuit, open circuit, ground fault, and overload.
Short circuit: occurs when two conductors come into contact with each other, causing a sudden increase in current flow.
Open circuit: occurs when there is a break in the circuit, preventing current flow.
Ground fault: occurs when a live conductor comes into contact with the ground, causing current to flow t...

- Q1. What is swing equations?
- Ans.
Swing equations are used to model the behavior of power systems during transient events.
Swing equations are a set of differential equations that describe the dynamics of power systems during transient events.
They are used to model the behavior of generators, transformers, and other components in the power system.
Swing equations take into account the mechanical and electrical properties of the system, as well as the pow...
- Q2. What is equal area criteria.
- Ans.
Equal area criteria is a method to determine stability of power systems.
It is used to analyze transient stability of power systems.
It states that for a power system to be stable, the area of the power-angle curve during fault should be equal to the area of the power-angle curve after fault clearance.
It helps in determining the critical clearing angle and time required for fault clearance.
It is based on the assumption t...
- Q3. What are the type of faults in power system.
- Ans.
There are various types of faults in power system.
Short circuit fault
Open circuit fault
Ground fault
Overvoltage fault
Undervoltage fault
Overcurrent fault
Underfrequency fault
Overfrequency fault
- Q4. Methods to solve load flow
- Ans.
Load flow can be solved using various methods.
Gauss-Seidel method
Newton-Raphson method
Fast decoupled method
DC load flow method
AC load flow method
Continuation power flow method
- Q5. Different sequence of current present in SLG, LLG, LLLG faults.
- Ans.
Different sequence of current in SLG, LLG, LLLG faults.
SLG fault has only one phase grounded, LLG fault has two phases grounded, LLLG fault has all three phases grounded
In SLG fault, the sequence of current is positive-negative-zero, in LLG fault it is zero-positive-negative, and in LLLG fault it is zero-zero-zero
These faults can cause damage to electrical equipment and must be quickly detected and resolved
- Q6. Motor EMF equations.
- Ans.
Motor EMF equations are mathematical equations that describe the relationship between the voltage generated by a motor and its speed and magnetic field.
EMF equations are used to calculate the voltage generated by a motor as it rotates.
The equations take into account the motor's speed, magnetic field strength, and number of turns in the coil.
The EMF equations are important for designing and optimizing motors for specifi...
