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 distribution transformer IS the term used to describe the utility transformer which supplies a residence.
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
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.
potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
Power transformers are step-up or step-down transformers used in the electricity transmission system, whereas distribution transformers are step-down transformers used in the electricity distribution system.
Both are same. This is an instrument transformer used for metering & protections.
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)
A '33-kV transformer' is a three-phase primary-distribution transformer, used in the UK's electricity system to step down the 33-kV primary-distribution voltage to the 11-kV secondary-distribution voltage -the lowest voltage used in the high-voltage distribution system. These transformers are categorised as 'power transformers', and are located in what are termed 'primary substations'.

A surge arrester is typically used on a distribution transformer to protect it from voltage spikes. This device diverts excess voltage away from the transformer, preventing damage caused by lightning strikes or switching surges. By clamping the voltage to a safe level, surge arresters help ensure the reliability and longevity of the transformer and connected equipment.
