ABB's fault current limiters are the efficient solution for short circuit current challenges in newly installed and existing electrical networks
The first trip mechanism acts to immediately trip to open contacts of the circuit breaker upon reaching a first threshold current level, and the second trip mechanism acts to trip to open the contacts once both a second current threshold is reached and a time delay has elapsed. The contacts ...

Evaluation of Breaking Capability of a Hybrid Fault Current-Limiting Circuit Breaker Based on Mayr-Type Arc Model The present study examines the breaking capability of a hybrid fault current-limiting circuit breaker (FCLCB) when a fault occurs at a distance l of 0, 1, ... E Calixte,Y Yoko...
In this paper, direct current (DC) fault current limiting and interrupting operation of hybrid DC circuit breaker (DCCB) using double quench, which consists of DCCB, a series resonance circuit, power electronic switch, surge arrestor, two separated current limiting reactor/resistor, and two supercon...
A modification of the basic circuit results in a solid-state ac breaker with current-limiting features. The operating characteristics of the fault-current limiter and the ac breaker are analyzed. An optimization procedure for sizing the superconducting coil is derived. (ERA citation 08:009763)Boenig...
Since the DC current has no zero-crossing in high-voltage and large-capacity DC scenarios, and the low line impedance results in a large growth rate of fau... X Yu,G Jia,YLM Liu - 《Energy Reports》 被引量: 0发表: 2023年 Parallel resonance type fault current limiting circuit breaker ...
