A Potential transformer is actually a instrument transformer that used in power systems to step down primary current voltages and secondary voltages from a higher level to lower secondary potential output voltage level. This transformer can be easily measured by the ordinary low voltage instrument like a voltmeter, wattmeter and watt-hour meters, etc.

PTs are made with special high quality core operating at lower flux densities in order to have small magnetising current so that no load losses are minimised. Both core and shell type constructions are preferred for PTs. For high voltages, core type PTs are used while shell type is preferred for low voltages.
