Current Transformers

Torotrans offers Current Transformers. It is used for electrical measuring instruments and electrical protective devices. It is very useful in high power circuits where the current is large. It is subdivided into measuring current transformer, which are used in measuring and indicating current, so as to reduce the line current to a value suitable for standard measuring instruments, relays, etc; and protective current transformers, which are used for over current and undercurrent relaying for power circuit protection. It is normally available as ring/ bar type and wound primary ring/ bar type. Wound primary current transformer has a primary winding of more than one full turn wound on core. It is wound on toroidal cores, which virtually eliminates error due to leakage flux. Adjusting the number of secondary turns may compensate for some errors.
