摘要

The increased dielectric loss is one of the comprehensive effects in insulating material from both the dielectric properties and the applied voltage, which causes the degradation of oil-paper (OIP) insulation especially when subjected to complex voltages. To quantitatively analyze the dielectric loss of OIP insulation, starting from the dielectric response characteristics of the bushing and the extended Debye model (EDM), the Runge-Kutta method is proposed to solve the EDM circuit. Taking four groups of measured waveforms of single type overvoltage and hybrid overvoltage as the typical instances of transient voltages, the active power loss of the OIP bushing is calculated and analyzed.
