MR Current transformer is a very useful device, it converts high AC current to small easily manageable value. 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 torpidly core of transformer. Furthermore, the secondary terminals are under a transparent sealable covers.
MR are manufactured in two types for measuring and protection.
- The accuracy class is designed by the highest permissible percentage current (ratio) error at the rated current perscribed for the accuracy class concerned.
- The Electronic Transformer s the standard sillicon steel core models,tape wrapping current transformer, low cost.
- The measuring current transformers can be used with or without foot and plastic cover.
- Current measurement, monitoring and piotection for electrical wiring and equipment.
- Current and power measurement for electric motors, lighting, air compressor, heating and ventilation system,air-condition equipment and automation-control system.
- Current, power and energy monitoring device.
- Relay protection device.
