Isolation Transformers are used to isolate one circuit from another. Highly sensitive circuits may require isolation from high power circuits, for example.

What or Which type of transformer can serve as both a ratio device and an isolating device?
Instrument Transformer
Can an isolating transformer have a center earth tap?
I suppose it could, but then it wouldn't be purely an isolation transformer. It would then be a isolation and either step up or step down transformer.
What is the rules as per transformer work?
Transformer works on the principle of Electromagnetic induction.
Difference between and rcd and an isolating transformer?
An rcd is a device designed to limit duration of electrical shock by disconnecting the circuit when a fault is detected. An isolation transformer is a 1 to 1 (same voltage and current in and out) transformer that keeps one part of an electrical system physically unconnected to another part of the system. It does this by using the principle of a transformer to allow current flow, without actually connecting the load to the source wires.
What is the pt transformer?
The abbreviation, 'PT', stands for 'potential transformer' (in Britain, the abbreviation is 'VT', and stands for 'voltage transformer'). This, together with a 'current transformer', falls into a category of transformer known as 'instrument transformers'. A 'PT' or 'VT' is used to reduce a high voltage to a level of voltage that can be safely read, remotely, by regular a.c. voltmeters or to provide inputs to high-voltage protection relays, while electrically- isolating the secondary circuit from the high-voltage primary circuit for the purpose of safety.

What are disadvantages autotransformer?
cannot be used as an isolating transformer, because is has common winding.
Can an isolating transformer have a center earth tap?
I suppose it could, but then it wouldn't be purely an isolation transformer. It would then be a isolation and either step up or step down transformer.
How voltage is measured in potential 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.
What is the purpose of auto transformer?
Helps with the starting of large electric motors.AnswerAn autotransformer is a transformer with a single winding, rather than two separate windings. It can be used as a step-up or as a step-down transformer, provided there is no requirement for electrically-isolating the secondary circuit from the primary circuit.
Why will or won't a transformer operate on AC?
transformer will work on ac

What is an instrument transformer?
An 'instrument transformer' is a category of transformer used to supply measuring instruments or protective relays. There are two types of instrument transformer: a 'voltage transformer' (known as 'potential transformer' in North America), and a 'current transformer'. They are used with high-voltage systems, where it is hazardous to connect instruments directly to such systems.Voltage tranformers are used to reduce high-voltages down to a level that can be safely applied to voltmeters, or to the voltage-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instruments (and personnel) from the high-voltage supply.Current tranformersare used to reduce high-voltage currents down to a level that can be safely applied to ammeters, or to the current-coils of wattmeters or energy meters, or to protective relays, while electrically-isolating those instrument (and personnel) from the high-voltage supply.
What is a voltage transformer and mention its function?
A voltage transformer (known as a 'potential transformer' in North America) is classed as an instrument transformer. It is used to reduce the voltage across a high-voltage load to a value that can be read (usually remotely) by an ordinary a.c. voltmeter, while electrically isolating that voltmeter from the high-voltage system for the purpose of safety. It can also be used to supply an input to a protection relay.
How do you work transformer?
The working of a transformer depends on the Faraday Law of Electromagnetic Induction.
Will 13.8 volt output transformer work for 13.5 volt transformer?
yes
What is the rules as per transformer work?
Transformer works on the principle of Electromagnetic induction.
