Current Transformer (low voltage)PDF
•MEASURING CT
Measuring current transformers are constructed to feed on other low voltage apparatus such as measuring instruments, relays, watt-hour meters (kW meter) and these type of current transformers are mainly used 0.5 and 1 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 transformer are mainly used 5P. (Customer supplied when required.)
