Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
Can the two end of a center tap transformer be use with out a rectifier?
The twoends of a center tap transformer cannot be used without a rectifier.
What is a transformer and what principle is used in transformer?
A transformer is a static device which converts electrical energy from one circuit to another circuit without changing frequency, power, power factor. It works on the principle of faradays laws of electro magnetic induction.
Can you improve the voltage level without transformer?
yes, we can incease voltage level by aplifiers.......
Can a 3 phase 415V- 1000V step up transformer operate correctly from 460V Ac supply without causing damage?
That's an 11% overvoltage (460/415), so this may be reaching the design limits of the transformer. If the system is actually run hot (say 105% of 460, or 480v), then I'd say no, unless specifically stated in test reports or design criteria. You should ask the manufacturer to be sure.
What is on load tap chenger?
A tap changer is used to vary the turns ration between the windings of a transformer to make minor changes to the secondary voltage. An on-load tap changer enables the turns ratio to be altered without disconnecting the transformer. An off-load tap changer requires the transformer to be temporarily diconnected. On-load tap changers are installed on the high-voltage side of the transformer, where the current is lower.
What type of transformer will convert 120V-60HZ US into U.K.voltage?
The standard residential nominal voltage in the UK is 230 V (-6%/+10%). So, for the purpose of selecting a transformer, a 1:2 ratio, 120/240 V, transformer will be an appropriate choice.The capacity (volt ampere rating) of the transformer must match or exceed the power rating of the proposed load. You should be aware, though, that transformers will not change the frequency of the supply, only its voltage.Another thing to be considered is the transformer's country of manufacture and where you intend to use it. For example, if the transformer is manufactured in the US, then it will be designed to operate at a frequency of 60 Hz.On the other hand, if it is manufactured in Europe, then it will be designed to operate at 50 Hz.A transformer designed to operate at 60 Hz will overheatif it is operated at 50 Hz, whereas a transformer designed to operate at 50 Hz will operate without overheating if operated at 60 Hz.This means that you will be able to operate a European transformer in the US without any difficulty, but operating a US transformer in Europe will result in overheating -unless it is operated BELOW its rated primary/secondary voltage.So if you intend operating a US made transformer in Europe, then you should obtain a 1:2 ratio transformer, but one rated at, say, 240/480 V. This will then operate without overheating at 120/240 V.

I just removed my cd changer on my mercedes c240 and the sound stops, any idea how i to get my sound back without cd changer
What is the voltage doubler using charge pump?
What is the math in a voltage doubler without a transformer? how doesa voltage doubler without a transformer?
What is meant by the term ideal transformer?
ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer
What is Auto transformer and ordinary transformer?
auto transformer is a one winding transformer which is are used for step up and step down voltage without chang its power and friquncy
What is the used of conductors in a transformer?
Without conductors, no current could flow -an essential requirement of a transformer!
Can you step down a 220v to a 110v without a transformer?
it can be done at the electrical panel with out a transformer. always have an electrician do it.
What happen if a transformer designed for 50 HZ and you operate it 500HZ?
If no other parameter will change then there will by only slight increase in core loss. However if frequency is increased 10 times transformer will be capable to accept 10 times higher voltage under same load conditions without saturating. This defectively increases transformer power capacity and cores loss will also increase in same degree.
How a rectifier transformer deffer from a power transformer?
rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
How do you install a CD Changer in a 1997 Eldorado without a stock CD player?
It depends on the make/model of the CD Changer. Most aftermarket headunits have a compatible manufacture made changer. If you do not have a compatible unit you can purchase an FM Modulator for that changer. The modulator takes the signal and broadcasts it over a radio frequency.
