A potential transformer (pt) is a static device used to step down high voltages to measurable levels in order to facilitate measurement and controllability. Since the voltage levels in the power system range well beyond kilovolt values, the transformers are used to bring the voltages down to an acceptable level used by protective relays.

A voltage transformer is used to convert the electrical output of a power source to match the voltage of your device, that is, to convert 110 volts to 220/240 volt or convert 220/240 v to 110/120 volt. A voltage ratio of 1:4 (read as 1 to 4) means that for each volt on the transformer primary, there is 4v on the secondary.

The energy applied to the primary must be in the form of a changing voltage which creates a constantly changing current in the primary, since only a changing magnetic field will produce a current in the secondary. N 1 = number of turns on the primary, n 2 = number of turns on the secondary, v 1 = primary voltage, v 2 = secondary voltage, i 1 = primary current, i 2.
