A Current Transformer steps down the high currents found in power systems to a level that standard current measuring instruments, such as ammeters and protective relays can safely measure. It does this by inducing a secondary current proportional to the primary current but at a reduced magnitude.Attributes:• High accuracy is for protecting equipment and ensuring its proper functioning.• To prevent equipment damage.• Capable of handling high voltage levels.Applications: A Current Transformer is a type of instrument transformer that is used to step down high currents in power systems to a level that can be easily measured and monitored by instruments, protective relays, and meters.
