What is a Current Transformer?

A current transformer is a type of instrument transformer that is used to reduce or multiply an alternating current. It converts a primary current into a secondary current through a magnetic medium. By producing an alternating current in its secondary winding, which is proportional to the current being measured in its primary, current transformers reduce high voltage currents to a much lower value and provide a convenient way of safely monitoring the actual electrical current flowing in an AC transmission line using a standard ammeter. 

What Does a Current Transformer do?

As the principal function of a current transformer is to determine the current in a circuit, current transformers are often used when a current or voltage is too high to measure directly. They are also known as step-down transformers, as they are able to reduce or “step-down” current levels from thousands of amperes to a standard output, either 5 Amps or 1 Amp. 

Current transformers are used to monitor high-voltage lines throughout the power grid, for detecting overcurrent, undercurrent, peak current, or average current conditions. They are typically found in generating stations, electrical substations and commercial electric power distribution, and are also used in domestic electric meters to measure electrical usage.
