How the doubly fed induction generator build up voltage?

If a self-excited generator lost all its residual magnetism, can it build up an output voltage?


How voltage is developed?

Voltage is a build up of electrons at one location relative to another location. To form a voltage gradient (difference), you need to somehow build up electrons at one location, or remove electrons from one location. Shuffling your feet on a thick carpet can do this!


Why you are generating ac not dc?

question is wrong....ac is generated in alternator <<>> The most likely reason is that there is no field voltage being generated. This is controlled by the voltage regulator. Check to see if you are getting a DC field voltage. On the voltage regulator there are terminals to different pieces of equipment on the machine. Look for the terminals that are designated F1 and F2. These should have a DC voltage on them. Also look for a potentiometer that controls the field voltage. Turn it one way and the voltage will go down and turned the other way the voltage will go up. Make sure that this potentiometer is in the correct position to allow voltage to the field coils.


What is the effects of more than one voltage source in a network?

Two voltage sources in series can either add up or cancel out depending on which way round they are orientated. If the two positive or the two negative terminals are connected together, the overall voltage is the subtraction of the two. If the positive terminal from one supply is connected to the negative terminal from another, the overall voltage is the sum of the two.


When conectring a step down transformer what is H1?

The H1 and H2 symbols on a transformer designates the two coil ends of the primary winding on a transformer. The symbol is the same regardless if the transformer is step up or down.AnswerIn North America, a transformer's high-voltage windings are identified by the letter H, and the low-voltage windings by the letter X. The 'start' of a winding is allocated an odd number, and the 'finish' of a winding is allocated an even number. For example, H1-H2 represent the start and finish terminals of a high-voltage winding, and X1 - X2 represent the start and finish terminals of a low-voltage winding.For a distribution step-down transformer, with the low-voltage terminals facing you and the high-voltage terminals on the far side of the transformer, terminal H1 is, by convention, alwayson the left-hand side of the transformer.When terminal H1 'goes positive' (i.e. is subjected to the positive half-cycle of the AC waveform), X1 also 'goes positive'.The identification of a transformer's terminals is important in order to determine the polarity of a transformer. Knowing a transformer's polarity is essential if two transformers are to be connected in parallel with each other.

How do you increase output voltage of a alternator?

The voltage output is controlled by the voltage regulator. Check to see if you are getting a DC field voltage. On the voltage regulator there are terminals to different pieces of equipment on the machine. Look for the terminals that are designated F1 and F2. These should have a DC voltage on them. Also look for a potentiometer that controls the field voltage. Turn it one way and the voltage will go down and turned the other way the voltage will go up.

How can static electricity build up an object?

If the object in insulated (or an insulator) , then that's what it does : build up until the voltage is great enough to jump the gap (to "ground").


How does electricity flow through a light?

A voltage is applied across the terminals of the light fixture to which the bulb is attached by two terminals, hot and neutral. A current then flows through the bulb. In an incandescent light the filament wire heats up and glows.

Why TRIACS blow?

You exceed the power dissipation capability of the device and it burns up. Too much voltage across the terminals , too much current being passed through it, reverse voltage spikes can all cause the triac to "blow".


How do you test voltage regulator on motorcycle?

Check the battery voltage, bike not running. Start the bike (crank the rpm's up a little), voltage should be a couple of volts more than battery voltage. Check both voltage (running and not running) at battery terminals. Charge voltage isn't all though, if it doesn't stop charging when it should it will boil the battery dry. If you are having this symptom, it's for sure the regulator


Can 3 of four batteries be wired up in series and 1 in parallel. Will this setup drain the parallel battery?

No it will impose the voltage of the three series batteries across the terminals of the paralleled battery. Batteries can only be parallel when all of the voltage potentials are near equal.


Can build up on a distibutor cap and build up on the wires cause it to missfire and sputter you cleaned them and it helped?

Anything that would allow the high-voltage to jump to the wrong place would certainly cause the engine to run poorly. Buildup around the outside of the cap would hold moisture which would allow the voltage to arc.
