Why does an alternators voltage rise when it is loaded down with a leading load?

∙ 6y ago
Because in the leading load or capacitive load the armature reaction is magnetizing.Here the stator flux adds up rotor flux and so the net flux of alternator increases and the net flux produces alternator's voltage.Hence the alternator's voltage rises.

Why does an alternators voltage drop sharply when it is loaded down with a lagging load?
An alternator's terminal voltage shouldn't drop 'sharply' when subjected to a lagging power-factor load. After all, most practical loads are inductive and it wouldn't do for an alternator's terminal voltage to drop 'sharply' for what is a normal load. Nevertheless, in common with most voltage sources, there will be a moderate drop in its terminal voltage due to the internal voltage drop caused by the load current passing through the impedance of the armature windings. Perhaps surprisingly, however, there may be an increase in terminal voltage when supplying a leading power factor, the reason for which can be demonstrated using simple phasor analysis of the alternator's induced e.m.f. and internal voltage drop -this cannot be shown here, but there are lots of websites which demonstrate this.
Summary of the step-down transformer?
A step- down transformer is one whose secondary voltage is less than its primary voltage, it is used to reduce 'step down' the voltage applied to it. The number of coils in the primary circuit is greater that the secondary circuit. For instance, to step down 480 Voltage to 240 voltage, you need a step down transformer whose ratio of primary coils to secondary coils is 2:1.
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
What the different between voltage generators and voltage transformers?
Generators generate and transformers step up or step down the voltage
Is there more current in the primary or secondary winding of a transformer?
The terms, 'primary' and 'secondary', describe how a transformer is connected and his nothing to do with which is the lower- and higher-voltage winding.The primary winding is the winding connected to the supply, while the secondary winding is the winding connected to the load. So, for astep-up transformer, the secondary winding is the higher voltage winding, whereas for a step-down transformer, the secondary winding is the lower voltage winding.For a loaded transformer, i.e. a transformer whose secondary is supplying a load, the higher-voltage winding carries the smaller current, while the lower-voltage winding carries the higher current.
The independent variable for a battery?
Its voltage remains constant unless loaded. The current available goes down as it is used up.
What cause diode failures in alternators?
Overheating/overworking the alternator expecting to charge a run down battery. Alternators are designed to maintain a battery not for charging a dead one.

Can videos be down loaded?
yes
What does laden mean?
burdened; loaded down.
What is transform function?
To stop up or step down the voltage
Would it be possible for the voltage regulator to be no good on two brand new alternators?
Probably not. You might do well to take the vehicle to an automotive electrical shop. They can track down problems quickly, no guessing. It IS possible, but VERY UNLIKELY. As answer 1 recommends, you need a qualified auto electrical technician/shop.
What is difference between retarding voltage and a voltage?
A retarding voltage is what causes the electronic to shut down.
How do you get the Punjabi font down loaded?
Kurie or mutiyar
What would happen with 130 volts in a normal ac outlet?
Usually voltage is between 110-130. Some of it depends on the transformers load or were the voltage tap is set. which brings up or down the voltage level. A simple adjustment. Higher voltage is better then lower, but form industrial standard 5% is max. Is the circuit Loaded up or is everthing turned on.. So 130.... is alittle high but should be OK for most equipment.
What component step down the voltage to the low voltage value?
Transformer
HOW do I SELECT A STEP DOWN TRANSFORMER?
By looking to the number of turns in the Primary and Secondary Coils. "A Step down transformers are designed to reduce electrical voltage. Their primary voltage is greater than their secondary voltage. This kind of transformer "steps down" the voltage applied to it."
