Why voltage of unit should match with grid when synchronising with grid?

If both the voltages do not match then there will be current fllow from higher voltage to low voltge, this is loss of power and can lead to even tripping of the system.

How do youelectrical synchronize?
You synchronize a generator to the grid by matching voltage and phase. Usually, but this depends on the particular system, you bring the generator's voltage to slightly higher than the grid, and its speed to slightly faster. At the moment of phase match, or slightly before, you close the tie-in breaker and simultaneously close the steam bypass valves. The generator should immediately pick up load. You then adjust exciter voltage to get your MVars right, and trim as needed.
What is the frequency of the secondary of a 230 volt step down transformer?
The frequency is dependant upon what electrical grid that you are connecting the transformerto. If you are connected to a 50 Hz grid, the transformer will output a voltage at 50 Hz. The same thing with the 60 Hz grid, the transformer will output a voltage at 60 Hz.
What is the reason for a grid voltage high?
There are strict standards relating to this. You should look up the standard that your power entity is under. With that said, a typical maximum may be 103 - 104%.
What is the purpose of a transformerin a power grid system?
A transformer changes the electricity from one voltage to another, which allows a high voltage power line to be converted down to a voltage suitable for home usage.
The saturation condition of a triode occurs when the plate is at high voltage values and the grid with respect to the cathode is?
Highly positive
Why is voltage regulation important in alternator?
because the voltage should be constant as the full transmission grid need ame voltage for synchronization of alternatos of grid

What voltage is the grid in an insectocutor?
The voltage can be anywhere from 5000 to 7500 volts. That is why the bugs snap when they get between the two grid plates.
Would grid electricity be used at home?
Not at high voltage. The Grid Electricity Is divided at subtations to lower voltage for transfer to Houses
What is the voltage of French national grid?
The voltage of the French National Grid is 2000 mw high voltage. It is a direct current electrical interconnector between the British and French transmission.
The voltage present in a power grid line is more than?
The voltage present in a power grid line is more than enough to kill you.
Vacuum tube grid current changes in?
In normal operation there is no grid current, only a voltage.
What are grid station?
Grid stations are the station which reduce the High Voltage to Low Voltage and increase the Current, the Current is Low and Voltage is High at the Generation Plant to reduce the energy losses during transmission of Electricity.
What is a definition of grid station?
it is a station which reduces high voltage to low voltage and increases current.
How triode valve can be used as an amplifier?
A 'Triode Valve' is a vacuum tube amplifier or switch of the simplest form. It has three parts: A heated cathode, a control grid and an collection plate anode.Electrons are emitted from the cathode and drawn towards the positive anode. Interposed between the two is a control grid that controls the cathode-to-anode electron flow by being charged appropriately, for example a negative charge (ground) on the grid will hamper the flow since the negative electron charge on the grid will obstruct the electron flow to the positive anode.OK, but the question was "use as an amplifier".In a triode, the anode current responds to the grid voltage, as explained above.Now, if a load (and the simplest load is a resistor) is placed between the anode terminal and the supply voltage, the anode current will create a voltage drop across the load resistor.If the anode current varies, so will the voltage across the anode load resistor.A varying grid voltage causes a varying anode current, so a varying grid voltage causes a varying voltage across the load resistor.Now, if one volt of grid voltage change only causes one volt of load resistor change voltage change, it's not much use.A triode can give a greater load voltage change than the grid voltage that caused it. This is amplification, where voltage out is more than voltage in.Typical voltage gains range from a low of just about 2.0 to high values over 70 times.
Why do wind turbines cause a voltage rise to the local grid?
They don't. The electricity they generate flows into the grid without any problems.
What is the function of grid?
it accelerate the motion of electron emitted by the filament if given a positive charge, similarly if negative voltage to grid the current flow through the grid is reduced. the more positive grid shows less current.
