Research on insulation state monitoring network technique for vessel electric network

Insulation state monitoring method of vessel electric network is analyzed. A method of locating insulation fault branches of AC and DC system is presented. It solves the influence of distributed capacitor to the ground of electric network branches when monitoring insulation, and also improves sensitivity and accuracy. A insulation state monitoring network system for vessel electric network is designed. Thereby, monitoring points can be selected. Distributed monitoring and real-time on-line remote monitoring can be implemented
