Abstract

This paper dealt with high speed breaking method to parallel arcing in low-voltage systems. The proposed high speed breaking circuit consists of a Rogowski coil and an integrator, and operates with an earth leakage circuit breaker (ELCB). A parallel arcing state was simulated by a short circuit using stripped wires. In this test, we analyzed tripping characteristics of the circuit breaker by the length of wires from 5m to 30m. From the experimental results, we confirmed that the proposed method can break the parallel arcing within a few millisecond.
