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.)
