Its core is composed of high-quality steel and works at low flux density. Its core is made up of silicon steel lamination.

The voltage transformer is connected with the circuit in parallel form. The voltage transformer is also known as a potential transformer.Ī current transformer is connected with the circuit in the form of series. There is no other name for the current transformer. The type of transformer that converts the high value of voltage into a low value is known as the voltage transformer. Comparison Chart Current TransformerĪ type of transformer that converts the high value of current into a low value is known as the current transformer. On the other side, the voltage transformer is used for measurement, as the power source and to operate a protective relay, etc. The current transformer is used to measure current and power, to operate the protective relay and to monitor the power grid operation, etc.

That is why full line voltage passes across the winding. On the flip side, a voltage transformer connected with the circuit in parallel form. Thus, full line current passes through the winding.

Current transformer connected with the circuit in the form of series.

The core of the current transformer is made up of silicon steel, while that of the voltage transformer is composed of high-quality steel and works at low flux density. There is no other name for the current transformer whereas voltage transformer is also known as the potential transformer. On the other side, the voltage transformer is the type of transformer that changes the high-value voltage into low value. Voltage TransformerĪ current transformer is the type of transformer that changes the current of high value into low value. The main difference between the Current Transformer and Voltage Transformer is that the Current Transformer is the transformer that converts the high value of current into low value, whereas Voltage Transformer changes the high-value voltage into low value.
