1. More advanced current probes combine a Hall effect sensor with a current transformer . 2. The current transformers are placed around opposite ends of a winding. 3. Current transformers permit the meter to be located remotely from the current-carrying conductors.4. Further investigation found that current transformers on the main transformer were improperly set. 5. Current transformers also have little effect on the primary circuit.6. The Power Delivery System ( PDS ) is a computer controlled three-phase current transformer . 7. Potential application of such sensors is connected with DC current transformers for special applications. 8. :There are some electrical devices which are rated in current, such as Current transformer . 9. That is, they acted as current transformers and energized lights using the induced power. 10. Devices used for this include Hall effect sensors, current clamps, current transformers , and Rogowski coils.
