A Current Transformer steps down the high currents typically found in power systems to a level that can be safely measured by standard current measuring instruments, such as ammeters and protective relays. It does this by inducing a secondary current proportional to the primary current but at a reduced magnitude.Attributes: • High accuracy is essential for protecting equipment and ensuring its proper functioning• Prevents equipment damage• Capable of handling high voltage levelsApplications: 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.
