The document discusses the breakdown mechanisms in liquids, highlighting that a single theoretical analysis cannot encompass all the factors involved. It describes various breakdown theories, including electronic breakdown, suspended particle mechanism, cavitation and bubble mechanism, stressed oil volume mechanism, and thermal mechanism of breakdown. This overview emphasizes the complexity of understanding liquid breakdown in high voltage engineering.

2. THE BREAKDOWN MECHANISM IN LIQUIDS
It is, therefore, not possible to describe the
breakdown mechanism by a single theoretical
analysis which may take into account all known
observed factors affecting the breakdown.

3. THE BREAKDOWN MECHANISM IN LIQUIDS
Breakdown theories are
 Electronic breakdown
 Suspended particle mechanism
 Cavitation and bubble mechanism
 Stressed oil volume mechanism
 Thermal mechanism of breakdown
