Online Identification of Transformer Internal Faults Based on the Parameters of the Operating Mode.


Q1: What is the reason for the analysis of mechanical damage to the transformer structure and not taking into account such emergency conditions as winding and inter-turn short circuits?

A1: It is precisely mechanical damage that is analyzed in the work, since it represents an early stage of damage, namely, the cause of the inter-turn and inter-winding short circuits.

Q2: How will the reference current-voltage characteristic corresponding to the operational state of the transformer be measured in practice?

A2: In practice, to measure the reference current-voltage characteristics of a transformer, it is necessary to assemble a measuring complex based on high-speed microprocessors under the control of software based on the developed method.
