Power Research & Development Consultants Interview Questions and Answers
18 Interview questions
MFC applications are still used due to legacy systems, familiarity, performance, and compatibility reasons.
Legacy systems: Many organizations have existing MFC applications that are costly to replace or upgrade.
Familiarity: Developers who are experienced with MFC may prefer to continue using it for new projects.
Performance: MFC applications can be optimized for performance in certain scenarios.
Compatibility: MFC a...
Faults in transmission lines can include short circuits, open circuits, and insulation breakdown.
Short circuits occur when two conductors come into contact, causing a sudden increase in current flow.
Open circuits happen when there is a break in the conductor, leading to a loss of continuity in the circuit.
Insulation breakdown occurs when the insulation material fails, resulting in leakage current or arcing.
Other f...

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
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 assumpt...
Faults in power systems are common and can vary depending on the system's size and complexity.
The number of faults in power systems can vary depending on the size and complexity of the system.
Faults can be caused by a variety of factors, including equipment failure, weather events, and human error.

Power systems refer to the network of electrical components and devices that generate, transmit, and distribute electricity.
Power systems involve the generation of electricity from sources such as coal, natural gas, nuclear, wind, and solar power.
Electricity is then transmitted through high-voltage power lines to substations, where it is distributed to homes and businesses through lower-voltage lines.
