Understanding the Concepts, Errors, and Influencing Factors of Current Transformers

Knowledge Base

Grasping Basic Concepts The Essence of Current Transformers Current transformers are fundamental devices in power systems, adept at converting high currents into proportionately lower currents. They are pivotal in both measurement and protection applications within power systems. Their key role is energy conversion, where they transduce high input currents to manageable, low output currents proportional…

Knowledge Base

From the image above, we can see that the three-phase power line and neutral line from the circuit breaker to the electrical equipment pass through the zero-sequence current transformer, and after the secondary winding of the differential current transformer is processed by the RCD detection and control device, to control the circuit breaker to trip. This is how the leakage…
