Difference Between Voltage And Current Transformer. As we know instrument transformers are used in AC. Current Transformer vs Potential TransformerCurrent transformers and potential transformers are devices that allow us to measure large currents and voltages.

VTs generally step down the higher voltage to a lower voltage so that it can be measured easily with the standard voltmeter. It carries load current. Current and voltage transformers CTs VTs as an integral part of protection chain.
It carries load current.
Jul 31 2017 Current transformers CT are broadly employed in order to measure high magnitude currents. Feb 12 2020 The output from the coil is a voltage signal proportional to the derivative of the primary current. Since no iron core is employed no saturating occurs unlike with traditional current transformers. For example if 150 amps flow through the 300 amp rated primary the secondary current would be 25 amps.
