Potential Transformer [Explained] in Detail

What is potential transformer ? The potential transformer is also known as an instrument transformer. Generally, is it used for alteration of voltage right from a higher value to a lower one. In simple words, we can say that a potential or voltage transformer is used to lower down the higher values of the voltage to a safer lever in order to measure currents as well as voltage associated with power transmission and distribution systems. Once stepping down of voltage to a safer value is done by the voltage transformer, voltage can be easily measured by using devices like voltmeter, watt-hours meters and wattmeter etc. Due to this property, sometimes, it is also considered as ‘step-down’ voltage transformer.
