Zero-loss deep current-limiting device
The zero-loss deep current-limiting device is a switching apparatus composed of a “converter” and a “current-limiting reactor” connected in parallel. The “converter” is a combined electrical apparatus that uses an electromagnetic repulsion fast circuit breaker as its main component and incorporates a measurement and control device for rapid detection of short-circuit currents. During normal operation, the “current-limiting reactor” is bypassed by the converter and remains in a loss-free state; it is only activated during short-circuit faults and automatically deactivates once the fault is cleared. This device can limit the magnitude of the original short-circuit current to below 50%.

Zero-loss deep current-limiting devices are typically used at locations such as the low-voltage side of main transformers, generator outlets, plant auxiliary circuits, and interconnection lines.
