Current TransformersCurrent transformers are electronic devices that are used to measure or monitor electric current in a circuit. They are commonly used in a variety of applications, such as power distribution, electrical metering, and protection circuits. A current transformer typically consists of a primary winding, which carries the current to be measured, and a secondary winding, which produces a proportional output current. The ratio of the primary to secondary winding determines the transformation ratio of the current transformer, and the output current can be measured or processed by other electronic components. The specific design and operating characteristics of a current transformer depend on the intended application and the range and resolution of currents to be measured. Some current transformers are designed to operate over a wide dynamic range and can measure both AC and DC currents, while others are optimized for a specific current range or type of current.
