Abstract

This study systematically analyzes the intrinsic correlation mechanism between insulation faults and operational energy consumption in high-voltage motors, revealing how insulation degradation impacts motor efficiency through mechanisms such as increased dielectric loss and elevated leakage current. By quantifying the energy consumption increment characteristics and long-term cumulative losses caused by various insulation faults, we establish an energy consumption-based insulation condition monitoring system. The proposed diagnostic approach integrates online monitoring of key parameters, early fault warning, and energy efficiency evaluation. Building upon this foundation, we develop an energy-saving-oriented comprehensive insulation protection framework, encompassing insulation system optimization, preventive maintenance strategies, and lifecycle cost minimization solutions. These findings provide both theoretical underpinnings and practical guidance for achieving efficient and reliable operation of high-voltage motors.
