A current transformer is a device which is used to produce an alternating current in its secondary winding, which is proportional to the AC current in its primary winding. This device is mainly used when a current or voltage is too high to measure directly. A split core current transformer is designed for electrical metering applications specifically designed to be installed around primary current-carrying conductors without disconnecting wires or breaking the monitoring circuit. These split core current transformers are the best solution for applications in energy measurement and management. These current transformers are specially designed for easy installation in applications like portable metering. Solid-core current transformers, which are used for permanent metering or revenue-grade applications, have a sealed core that protects the sensor from debris that can reduce accuracy. In contrast to split-core installations, the conductor must be disconnected during solid-core installation.

IPD offers current transformers from globally leading brands such as ABB, SOCOMEC and Veris. Split core current transformers come with a current ratio of up to 5000/5, and solid core current transformers, in up to 4000/5. In most applications, measurement accuracy directly affects the efficiency of an overall system. The accuracy of the power calculation depends on the accuracy of the current sensors. A class 1 power meter requires current sensors with accuracy much better than 1%, most of the CTs offered at IPD have an accuracy class of 0.5 thus ensuring efficient measurement. Application specific current transformers such as modular, primary wound and plug-in CTs are available along with suitable accessories.
