Either the load is changing or there is something wrong with the testing method or there is no voltage regulation and the voltage is varying wildly.

What is voltage sweep generator?

A: Sometimes a spectrum of frequency must be analyzed a voltage to frequency converter can be used to sweep a range of frequency just by changing some DC level.


What is the purpose of a tone generator?

A major purpose is to generate test signals for troubleshooting purposes. Sometimes they are also used for sound effects generation for plays, movies, radio dramas, etc.


Why DC battery is required for generator?

The starter motor of a diesel generator is a DC motor. Depending on the size of the diesel engine the starter motor could be 12 volts or 24 volts. Sometimes more that one battery is used at the specific voltage. These batteries are connected in parallel to create more amp hour cranking power.


How long can the maximum ampere rating on a generator be exceeded?

Sometimes only seconds, it depends on the way the manufacturer rated the "maximum" capacity. In general, electrical equipment should be operated at no more than 1/2 of a maximum capacity.


What is dc separately excited shunt generator?

Either or both can be separately excited. To generate voltage you need a big magnet( the field). Most generators use an electro-magnet. Now the electro-magnet needs a source of power (electricity). We could use the generators own output to excite the field (magnet), this is called self excitation. The problem with self excitation is that we have to wait for the generator to turn and start generating, also to start generating (Building up) there must be some left over magnetism from the last time it was run (called residual magnetism) or not even a little voltage will be generated to start the field current flowing. To solve these problems we could use separately excited. This means we must have a separate source of power to excite the field to produce the magnetism. Sometimes a battery or gasoline driven generator is used to excite the field of a very large generator to get it generating and then we can use some of the generated output to either recharge the battery or switch over to from the battery. In any case we have adjustable control of the generator all the time. This is why most generators are designed to be separately excited. And that is why you car has a voltage regulator. It wakes up the alternator when the engine is started by separately exciting it (the field) with the battery and then regulates the output voltage of the alternator as the engine changes speed with the driver's commands from the gas pedal.

Is generator used in nuclear or solar energy?

Generators are nearly always used for nuclear power, and sometimes used for solar power. In nuclear power plants, the reactor makes steam to run a generator. Much of solar produced electricity does not use a generator, but produces power through a photovoltaic effect. Concentrated solar can be used to make steam to run a generator.

Is it possible to change the frequency in an electrical substation?

yes, it is possible to change the frequency in substations. frequency changer is a motor-generator set that changes power of an alternating current system from one frequency to one or more different frequencies, with or without a change in the number of phases, or in voltage. Sometimes a converter is used to accomplish this.
