摘要：
The paper presents result of analysis of dielectric response in frequency domain for several power transformers. The main goal of this analysis is determination of moisture content in solid insulation. It is result from the authors experiences that same basics information required to correct analysis are unavailable or uncertain in many cases. Authors carried out analysis of dielectric response for power transformers taking into consideration the fact that the geometry and temperature can differ from initially assumed.
