Voltage Transformer Product Details:

General:
Instrument transformers include Current transformer (CT) and voltage transformers (VT) (potential transformers (PT)).

 

PT is used for measurement of voltages. It has a large number of secondary turns and a fewer number of primary turns. They are used to increase the range of voltmeters in electrical substations and generating stations. It works along the same principle of other transformers and converts voltages from high to low. It will take the thousands of volts behind power transmission systems and step the voltage down to something that meters can handle.
