It is called static excitation when you make use of solid state components like diode and thyristors to convert to pure dc and to use this dc for field excitation of synchronous generators. The field winding of synchronous generators can be excited by dc source only. It is called brushless excitation because use of carbon brushes are not made here.It is called dynamic excitation is when you make use of rotating brushes. Excitation is necessary to produce reactive power and also to regulate the voltage of synchronous generators.

What is the difference between differential pressure and static pressure in a fluid system?
Differential pressure is the difference in pressure between two points in a fluid system, while static pressure is the pressure at a single point in the system.
What is the difference between static pressure and differential pressure in fluid dynamics?
In fluid dynamics, static pressure is the pressure exerted by a fluid at rest, while differential pressure is the difference in pressure between two points in a fluid system. Static pressure is uniform throughout a fluid at rest, while differential pressure measures the change in pressure between two different locations within the fluid.
What is the Difference between static equilibrium's and dynamic equilibrium?
Static equilibrium refers to a system at rest where all forces are balanced, while dynamic equilibrium refers to a system in motion where the rate of change is constant. In static equilibrium, objects are stationary, while in dynamic equilibrium, objects are moving at a constant speed and direction.
What is the difference between static pressure and dynamic pressure, and how do they affect the performance of a fluid system?
Static pressure is the pressure exerted by a fluid when it is not in motion, while dynamic pressure is the pressure exerted by a fluid when it is in motion. Static pressure affects the overall pressure within a fluid system, while dynamic pressure affects the velocity and flow of the fluid within the system. Both static and dynamic pressures play a crucial role in determining the performance and efficiency of a fluid system.
What instrument is used to measure the speed of an airplane?
A pitot tube is typically used to measure the airspeed of an airplane. It is connected to an airspeed indicator in the cockpit, which displays the speed based on the pressure difference between the pitot tube and static port.
What are the seminar topics related to power system engineering?

What is the difference between differential pressure and static pressure in a fluid system?
Differential pressure is the difference in pressure between two points in a fluid system, while static pressure is the pressure at a single point in the system.
What is the difference between continuous and discrete system?
The difference between continuous and discrete system lies in the variables. Whereas the continuous systems have dynamic variables, the discrete system have static variables.
What is the difference between generator over excitation versus under excitation when attached to the grid?
Over Excitation is a condition when the Excitation System is providing too much field current and as a result, the rotor of the generator will over heat. The Excitation System is equipped with an Over Excitation Limiter. This limiter acts to reduce the Excitation Current if this condition exists Underexcitation is a condition when the generator is not getting enough Excitation Current. If the generator does not get enough Excitation Current, it can be un-synchronized with the grid. We call this slipping a pole. If this occurs, the generator can be severely damaged.

Differentiate between static and dynamic systems in linear system analysis?
If a system is static then it will be known as STATIC SYSTEM and if it is not static then its a common sense that it will be a DYNAMIC SYSTEM.
