Clamp type current transformer CT313
Split core current transformer design is used for energy efficiency monitoring and automation applications. These include sub-metering cost allocation, dynamic energy consumption and peak load analysis.
ZTC series of AC Split core current transformers are a simple to use, compact split-core design which is easily installed for metering applications. They are ideal for distributed measurement systems and can be retro-fitted into existing installations and non-interruptible equipment as there is no requirement for disconnection and re-connection of wiring.
