Research on AC Superposition Method of On-line Monitoring of XLPE Cable Insulation
Abstract:As the damage of XLPE power cable insulation is usually caused by water tree deterioration, it is very important to make on-line diagnosis on it. Bases on the theoretic analysis of AC superposition method, this paper analyzes the detecting principle of 101Hz signal and established the equivalent model to carry on the simulation analysis.
Keywords: XLPE power cable on-line monitoring AC superposition method
