Distribution transformer vs main transformer

Transformer Step Up Transformer in order to reduce current to it secondary column has the potential transformer is a step down Transformer in order to use the potential difference across it. 

 We will go to learn the difference between current transformer and potential transformer.

Transformer cannot be open circuited on and circumstances when it is on the service that secondary a button for my can be constructed without any damage being caused to the operator of the Transformer Transformer may be considered as a series Transformer potential Transformer is considered as a transformer the  primary current in a current transformer is independent of the secondary circuit and the primary current of a potential Transformer depends upon the secondary circuit conditions.

 The primary winding of the current transformer is connected in series with the Line  the current to be measured and it carries the full line current the primary winding 

potential transformer is connected across the line of voltage to be measured hence the full line voltage and current across  its terminals.  Current transformer of 5 ampere and it can be used to measure a high-current Lite 200a with the help of a potential Transformer a 120 volt 1 amp.  Meter can be used to measure when High Voltage.
