A CVT (Constant Voltage Transformer) is always better than a Servo Stabilizer. But a CVT is costlier than a Servo Stabilizer of same rating.

What is the effect of low impedance transformer on regulation?
The lower the impedance, the lower the voltage drop across the transformer as it is loaded. This means regulation is better, since voltage variance is smaller.
How do you increase a voltage?
If you are dealing with AC voltage, you can use a transformer. You can find transformers at places like Radio Shack, Jaycar and some online sites like eBay. Transformers have to be connected in the right way. You have to connect the voltage you are going to increase to the low voltage side and on the high voltage side will be the voltage which has been stepped up by the transformer. (If you want a DC voltage out, you will need to connect a bridge rectifier to the output, followed by a large capacitor and then a voltage regulator of the voltage you want out.) If you are dealing with DC voltage then you will need a chip to step the voltage up. These chips can step voltage up from around 1 to 10 volts to at least 20 to 30 volts. These chips also need to be connected correctly. You will need more components than using a transformer. You will probably need some capacitors and some resistors. Depending on the IC you choose, you will find many circuits on Google for it and how to build them. By far the easiest type of voltage to step up is AC. If you have the option of AC, and need to have a very high voltage output, you are better off using a transformer, bridge rectifier and a rectifier.
How does a transformer change voltage and current?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
What is the expriy date of 11 KV Transformer oil?
It is better to check the BDV (Break down voltage) of the oil to decide whether the said oil is usable for 11KV application, instead of depending upon its "expiry" date.
Basic operation of a 3-phase transformer?
Three Phase transformers have three windings. If connected in Delta, it will have R Y B phase winding, voltage between RY, YB and BR. Phase voltage and line voltage are same. If connected in Star, there will be a neutral as well with RYB. Line voltage and Phase voltage are different. Line voltage = 1.73 x Phase voltage.

Can 240v tools be converted to 110v?
It would be better if you got a transformer and stepped up the voltage.
Can you use a transformer to compensate the voltage drop in a branch circuit?
If the voltage drop is excessive, it is a sign that the circuit conductors may be undersized. Better to install larger conductors. If you try to use a transformer, under light loads the voltage will rise to unacceptable levels, possibly damaging equipment.
What is step up transformer?
To transmit a lot of electrical power, you either need a high voltage or a high current. But a higher current means your cables got hotter and you lose a lot of energy so is better to use higher voltage. To increase the voltage, we need to use a step up transformers. Step up transformers are transformers which has ability to increase the voltage and they have more turns on the secondary coil on the primary coil.
Why is sma welding current referred to as constant current?
because the current is regulated rather than the voltage all the motions are controlled by movement that has been programmed. you cant see whats going on with the arc so to make adjustments you have to reprogram the motion after you stop and see what happened. perhaps you can set it for constant voltage and get better results. perhaps constant voltage is better for different materials. most smaller wire feeds are constant voltage which tends to keep the arc length constant. the operator can watch what he doing if he can see the arc and can make all manner of small adjustments. without reprogramming the controls. stick welding is possible because you can watch what you are doing to keep arc length constant the machines are almost always constant current
In a transformer primary or secondary will inside winding?
A step-down transformer's primary is high voltage and secondary is low voltage, based on voltage configuration or load we select which winding we do fast.In air-cooled Transformers output voltage is high and load current is low. So in air cooled low voltage winding in side and high voltage winding in out side of the coil . So we can reduce high voltage short problems and we can easily provide coil insulation . reduce short problem. It is cooled in oil.In step-down transformers we can do high voltage inside of the coil and low voltage and high current of the coil is outside. Because we can better coled in outer side . and reduced to temp problems.AnswerThe terms 'primary' and 'secondary' do not relate to a transformer's voltages, but to how its windings are connected. The primary winding is connected to the supply and the secondary winding is connected to the load. So, for a step-up transformer, the secondary winding is the higher-voltage winding while, for a step-down transformer, the secondary winding is the lower-voltage winding. Your question, therefore, should ask whether the higher- or the lower-voltage winding is the 'inside' winding (i.e. the winding closest to the core), and the answer is that it is the lower-voltage windings are innermost and the higher-voltage windings that are outermost.
Why zener diode is used as voltage regulator?
A: At one time it was used for a regulator because in the reverse voltage breakdown it has the characteristic of keeping the voltage constant as voltage is increased. IT has being replaced by many three terminal regulator with much better regulation and temperature coefficient
Why transformer rated in KVA instead in KWH?
VA, or volt-amperes, is a measure of the output of the transformer. VA is also called apparent power. Watts on the other hand, is also called true power. If the transformer feeds a resistive load, then watts are equal to VA, because the voltage and current are in phase. If the transformer feeds a reactive load, such as a motor, then the voltage and current are no longer in phase, and the true power (watts) is less than apparent power. Since the true power, or watts delivered can change depending on the load, it is not very useful as a transformer rating. The VA remains constant irregardless of the load characteristics, and so is a much better indicator of transformer performance.

What is the use of a transformer with turns ratio 1?
isolation if you are in the usa and must service electronics the neutral is grounded the power supply is a voltage doubler one side is 170v+ to ground the other is 170v negative to ground so if you run the power thru the transformer first you stand a better chance of staying alive these transformers are quite often used to trigger scrs or triacs for the same reason
