The main advantage of the potential transformer is which can be calibrating the high voltages by using of the secondary winding connected to the small voltmeter
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.
It's a PT (potential transformer) that's attached to the bus.
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
The potential transformer is used in the electricity supply industry to measure accurately the voltage being used. The current transformer is basically a step down transformer.
what are the advantages of using instrument tranformers
Both are same. This is an instrument transformer used for metering & protections.
CT=========current transformer PT=========potential transformer these are the instrumental transformers.
No actually not, there are many differences in so many things (1)Size:- Potential transformer has very smaller size then Power Transformer. (2)Capacity:- Power transformer is designed to work on kilo amperes where potential transformer has almost negligible current during operation. (3)Utility:- Potential Transformer is used to convert very high voltage to very low voltage and output is connected to a voltmeter which is calibrated accordingly to measure high voltage,where Power Transformer is used in transmissions of power supply.

A potential transformer steps the high voltage down to a level of 120 V to measure them safely and easily.
I'm not quite sure what you mean by a "potential transformer", but I look at it this way: The transformer isn't aware of the purpose to which you're putting it, so no matter what you call the function, the transformer continues to perform it ... transforming voltages and impedances in proportion to the turns ratio, and currents in proportion to its inverse.
A current transformer is a donut (toroidal) shaped transformer. You use it to measure current (expressed in amperes). You run your wire to be measured through the transformer and it produces a variable output based on the current.A potential transformer is basically a high ratio transformer that is used to measure voltage on high-voltage lines. For example: They will use a 10:1 ratio potential transformer to convert 4160v to 416v. Then they can measure this lower voltage with a meter. The meter then applies a user programmed multiplier (10) to this number to calculate the voltage.
A capacitive voltage transformer (CVT) uses a (usually two) stacks of capacitors to reduce the votlage to a smaller internal potential transformer (PT). This makes them less expensive than an equivalent PT, but there can be a loss of accuracy.
A 'potential transformer' is the North-American term for what, elsewhere, is called a 'voltage transformer'. This, together with a current transformer, is classified as an 'instrument transformer', and is used to (a) reduce high-voltages to safe levels for metering or protective-relay applications, while (b) electrically-isolating the secondary circuit from the high-voltage primary circuit for reasons of safety.The term, 'potential device', is too vague to mean anything specific, but could be used to describe any device that operates at some potential with respect to earth (ground).
advantage and disadvantage of three phase transformer connections
advantage and disavavtage of transformer
By connecting a voltmeter across the secondary terminals of the voltage/potential transformer. The transformer acts to reduce the voltage applied to its primary winding, while electrically-isolating the primary (usually high-voltage) circuit from the voltmeter.
The main use of a transformer is to change an AC voltages from one potential to another. The AC voltage can be raised from lower potential to a higher one or from a high potential to a lower one. The voltages are determined by the ratio of turns between the primary coils to the secondary coils for each individual transformer.

potential transformer is that which transforms one range of voltage (potential difference ) to another range without changing frequency.AnswerA 'potential transformer' is the North American term for what, elsewhere, is called a 'voltage transformer'. It, together with a current transformer, belongs to a class of transformers known as 'instrument transformers'.Potential transformers are used to (1) reduce the value of a high-voltage supply to a lower value (often 120 V) so that it may be read by ordinary voltmeters, and (2) to electrically-isolate the voltmeter from the high-voltage source for the purpose of safety.In electricity substations, potential transformers are also used to provide an input to certain types of protective relay.
