Research on Insulation Detection and Fault Location System of Ship Power System

Ship electrical power System is complex and power load is often composed of all kinds of equipment. Accidental power failure often causes severe incidents, significant casualties, devices damage and money loss. Traditional insulation detection includes balanced bridge and differential current detection. Nevertheless there are some problems on traditional methods, including poor reliability, being influenced by capacitance Leakage, small measurement range and low measurement accurate. This article provides a real time online inspection system for ship electrical power, which inspects ground insulation and capacity leakage. Besides, it can also provide faults location, transport data to management platform, set parameters, record alarm data and human machine interacting interface. The insulation detection and fault location system has a high accuracy and well effects.
