Research on Transformer Winding Fault Detection Method Based on the Voltage and Current Characteristics of LISSAJOUS

摘要

Transformer power system is one of the most important electrical equipment, winding transformer failure is an important cause of damage and threaten the safe operation of the power grid. Through theoretical analysis, we propose a Lissajous analysis of transformer voltage/current characteristic analysis method to detect winding faults, while the design of the experimental method, by specific experiments further confirmed Lissajous characteristic analysis method based on effectiveness of transformer winding faults provides a new detection method.
