How do current transformers provide relay protection
The potential transformers (PTs) and current transformers (CTs) usually produce electrical signals which monitor the state of current and voltage in a system. This. Differential protection compares current entering and leaving the transformer. It is the most sensitive protection for internal winding. It is normal for a modern relay to provide all of the required protection functions in a single package, in contrast to electromechanical types that would require several relays complete with interconnections and higher overall CT burdens. Basler Electric is a manufacturer of excitation systems, voltage regulators, genset controls, protective relays, custom transformers, and injection molded plastic components.
