Current Transformer (CT) is used to transform the high AC current to small easily manageable values. They're connected with the Panel Meter or Relay and they can help to measure the current or protect the equipments. Low voltage current transformers are manufactured as of two types for measuring CT.

• Measuring CT: Measuring current transformers are constructed to feed on other low voltage apparatus such as measuring instruments, relays, watt-hour meter (KW meter) and these type of current transformers are mainly used 0.5 and 1.0 class to transfer the current from highest rated current to rated secondary current.
• Protection CT: Protection current transformers are constructed to feed the protection relay. These type of current transformers are mainly used 5P. (Customer supplied when required.)
