Efficient Methods to Reduce Arc Effects in Circuit Breakers

Abstract

Abstract: This paper investigates the opening and non-opening processes of low voltage circuit breakers, the arc effects during short-circuit currents, and seeks to identify practical solutions to minimize potential damage. The reliable operation and protective capabilities of circuit breakers are crucial in power systems, especially during adverse conditions. Arc currents are a significant component of short-circuit scenarios in power systems. Additionally, arc currents typically occur between contacts during the opening of circuit breakers under normal conditions. Therefore, the components of circuit breakers play a vital role in mitigating the current flowing through the system. To diminish the destructive effects of electric arcs on circuit breaker parts, maintaining constant current values in the system is necessary, alongside conducting requisite tests and data collection. Understanding the properties and impacts of the components within the circuit breaker is also beneficial.
