N2 - Three scenarios can be observed in polar dielectrics (deionized water and ethanol) under a nanosecond positive HV pulse depending on HV pulse amplitude. Two discharge modes ('bush-like' and 'tree-like') and cavitation mode are characterized by different morphology, propagation velocity and initial pressure. Dynamics of cavitation mode is analysed in terms of Rayleigh model. Initial cavity size in deionized water, ethanol and n-pentane agrees with the predictions of numerical simulations performed by other authors.
