A method for blocking and detecting low impedance arc discharge of a circuit breaker for a low voltage is provided to rapidly block a circuit breaker by detecting permanent or temporary short circuit in a voltage distribution system on a real time. An arc current detecting part(110) detects an...
The total tripping time of the OCRs is limited by the relays and network operation constraints as regards. 3.1.1. Coordination Criteria The selection of CTI is fundamentally depended on the tripping time for the primary OCR, overshooting time, and the clearing time of breaker. The time ...
