Noted: For measuring current transformers, the accuracy class is designated by the highest permissible percentage current (ratio) error at the rated current prescribed for the accuracy class concerned.

Note: When the MR add with shell ,it will be called MRT

2.Outline drawing

MR Current transformer is a very useful device, because it converts high AC current to small easily manageable value. Current transformers consist of primary winding, secondary winding, magnetic core and insulated body. If current transformers have no busbar, they are manufactured without primary winding. Instead of this, it is possible to constitute primary winding by passing conductor or busbar inside toroidal core of transformer. Our current transformers are produced according to IEC IEC44-1. Furthermore, the secondary terminals are under a transparent sealable covers. Low voltage current transformers are manufactured in two types for measuring and protection. Measuring current transformers: Measuring current transformers are constructed to feed on other low voltage apparatus, such as measuring instrument, relay, watt-hour meter (kW meter), these types of current transformers are mainly used 0.5 and 1 class to transfer the current from highest rated current to rated secondary current.Protection current transformers: Protection current transformers are constructed to feed the protection relay. These type of current transformers are mainly used class 3.
