In synchronous system while generator generates rated power and load increase in system, Than frequency start goes to down respectively same as rpm of the all generator start reduce but the speed of the rotating magnetic field is same, So the angle created between rotating magnetic field and generator rotor, This angle are known as load angle of generator.
(In isolated system there is same as synchronous system, Load angle very sharply increase in isolated system than synchronous system cause in the isolated system the access load share only by the particular machine while in the synchronous system there is share with all connected machine, which is very small other than)

What is the angle that measures 170 degrees?
It is an obtuse angle. It is an obtuse angle. It is an obtuse angle. It is an obtuse angle.
What is the negation of angle a is a right angle?
It is: "angle a is not a right angle" or "angle a is greater than or less than a right angle".
Supplements of the same angle are congruent what's the best statement for reason 6 of this proof?
angle B and angle D are supplements, angle B is congruent to angle D, angle A is congruent to angle A, or angle A is congruent to angle C
what type of angle is angle 98?
An angle of 98 degrees is an obtuse angle
What type of angle is a 12 degree angle?
A 12 degree angle is an acute angle.
What is the phase angle difference between inductive load and resistive load?
The phase angle is defined as the angle by which the load current leads or lags the supply voltage.For a purely-resistive load, the phase angle is zero, because the load current is in phase with the supply voltage.For a purely-inductive load, the phase angle is 90 degrees lagging.But few loads are either purely-resistive or purely-inductive; typically, most loads are resistive-inductive. This means that, typically, the phase angle lies somewhere between zero and 90 degrees.
In a capacitor circuit load angle is?
Negative.
What is limit load factor in aviation?
the maximum load factor without structural damage to the aircraft. Load factor = 1 / (cos (angle of turn))
What is the effect of changing the firing angle?
Changing the firing angle affects the conduction angle of the AC voltage waveform supplied to the load in AC-DC converters like controlled rectifiers. By altering the firing angle, the average output voltage and hence the power delivered to the load can be controlled, affecting the speed or intensity of the load, like in motor control applications.
How do I know or calculate the load that a 2 inch .25 thickness angle iron can support?
First, consider how the angle is supported and how the load is applied, then apply the applicable Strength of Materials equations for that case.
How do you decide KVAR rating of capacitor bank?
The KVAR rating of a capacitor bank is typically determined by the reactive power (KVAR) demand of the system that needs to be compensated. This can be calculated by conducting a power factor study or analysis to determine the required amount of capacitive reactive power to bring the power factor to the desired level. The KVAR rating of the capacitor bank should be selected to meet this calculated KVAR demand.
What is the physical meaning of power angle in a power system?
a curve drawn for power against load angle maximum power occurs at load angle of 900 maximum power will be transffered from sending end to receiving end when the reactance is 1.732 times its reactance
What is the formula for phase angle?
Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.
What does zero leading power factor mean?
A 'leading' power factor indicates that the load current is leading the supply voltage. Since power factor is the cosine of the angle by which the load current either leads or lags the supply voltage (i.e. the load's phase angle), a cosine of 0 corresponds to a phase angle of 90 degrees. So, a power factor of 0 (leading) indicates that the load current is leading the supply voltage by 90 degrees, which means that the load must be purely capacitive.
What is extinction angle control?
extinction angle control is a scheme of forced commutation for power factor improvement in phase controlled convertors/rectifiers. In this scheme the firing angle is adjusted in order to get the desired output or load voltage. By varying the value of extinction angle we can get the desired load voltage and current waveform.......submitted by abhimanyu(sunny)
What is the power factor when the current and voltage are in phase?
The power factor of a load is the cosine of the angle by which the load current lags or leads the supply voltage. So if they are in phase (phase angle is zero), then the power factor must be unity (1).
How can you fix the output current of phase angle?
Your question doesn't really make much sense. Phase angle is simply the angle by which the load current leads or lags the supply voltage.
