Experimental studies on electrical breakdown field strength of electrode with water mist containing MC additives

Water mist is one of the effective candidates for halon replacement used in electrical environment fire protection. Water mist additives may greatly enhance fire suppression effectiveness. In electrical environment, electrical breakdown field strength (E) is one of the important factors that control the performance of electrical equipment. In this study the variation principles of electrical breakdown field strength and the electrical characteristics of MC additives were investigated by electrode discharging experiments. Experimental results showed that electrical breakdown field strength was impacted obviously by the conductive metal ions and insulated fluorocarbon surfactants in MC additives. The attenuation percentages of E in different experimental cases were described, thus providing scientific guidance for the use of water mist and MC additives in electrical fire suppression.
