Introduction to Protection Transformers
Protective Current Transformers are designed to measure the
actual currents in power systems and to produce
proportional currents in their secondary windings which are
isolated from the main power circuit. These replica
currents are used as inputs to protective relays which will
automatically isolate part of a power circuit In the event
of an abnormal or fault condition therein, yet permit other
parts of the plant to continue in operation.
