What effect if load increase in electrical system?
when load on the electric system increase frequency of the system will decrease resulting in higher intake at powergenerators. If higher intake is not net by powergeneration stations entire power system will collapse. It is called grid failure.Another AnswerAn increase in load will result in an increase in load current.
What is the difference between resonance and resonant frequency?
resonance is the behavior of resonant frequency while resonant frequency is the cause of it. There are basically two types of resonance; Electrical and Magnetic. Resonant frequency is that particular frequency for a system for which the system performs its best. while the system at that particular situation can be called the system at resonance
What is the deviation ratio for frequency modulation?
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
What is the function of a repeater in terrestrial microwave transmission?
Repeaters may be installed with each antenna to increase the distance served by terrestrial microwave.Repeaters received the signals and converted into transmittable form and pass it to the next antenna.Repeaters can broadcast the regenerated signal at its original frequency or at modified frequency depends on the system
What is frequency dead band in turbine control system?
it is range of frequency variation for which governor does not take any proportional corrective action.
What will the sympathetic nervous system do to the cardic muscle?
Sympathetic nervous system activation will increase the frequency and force of cardiac myocyte contractility

What is the effect of increasing speed droop on governor of hydro electric generator?
I would suggest what you mean is to increase speed droop sensitivity. That mean you reduce speed droop percentage set point. I will answer primary impact only assuming your plant is grid connected. Assuming your current speed droop percentage set point is 10% and you have a 100MW hydro turbine generator serving a 50-Hz grid system. Therefore your droop response due to system frequency deviation is 100MW for every 5Hz (10% of your system nominal frequency of 50 Hz), or +/- 20MW/Hz or 2MW/0.1Hz. What this number does? It will be used by your governor to compensate the load of your hydro turbine as system frequency deviates from the reference frequency. As system frequency increases by 0.1Hz, the governor will subtract generator output by 2MW from the current load set point. If system frequency decreases by 0.1Hz then the governor will add 2MW to the current load set point. This is done automatically. Now you want to increase its sensitivity of your governor from this set point to 5%. You are actually doubling the response. That means the new load response will be +4MW/0.1Hz if unit system frequency reduces from the reference frequency and -4MW/0.1Hz if system frequency increases above the reference frequency. If you increase the sensitivity further to 2.5, then the new response will be +/-8MW/0.1Hz.
What is the frequency deviation for frequency modulation?
Deviation ratio: In a frequency modulation system, the ratio of the maximum frequency deviation of the carrier to the maximum modulating frequency of the system under specified conditions
If frequency increased is that more hazardous or less hazardous?
The answer depends on frequency of what! It the frequency of safety checks is increased then it makes a system less hazardous. If the frequency of changes to he system is increased, the system becomes more hazardous.
What occurs if the frequency of a force applied to system matches the natural frequency ofvibration of the system?
Resonant

What is the frequency at which a system oscillates when it is disturbed called?
Natural Frequency
If you multiply the system bus frequency by the multiplier you get the?
processor frequency
If you multiply the system bus frequency by the multiplier you get what?
processor frequency
Why must the oncoming generator on a power system be parralleled at a higher frequency than that of the running system?
If the frequency of the oncoming generator is slightly higher than the system frequency, the phase angle between the system and generator voltages will slowly change at a frequency equal to the difference between system and generator frequencies.
What is crossover frequency?
Gain crossover frequency is the frequency at which a system's magnitude is equal to unity, or 1.
