Abstract :
The computer program “Bubbreak” is designed with two purposes: educational and research. It consists of three parts: computation of prebreakdown time duration t(E, P, T, r0) according to the bubble model of breakdown initiation, graphic simulation of prebreakdown processes in the gap with the visualization of bubbles on electrodes, mathematical treatment of t(E, P, T, r0 ) to get E(t)|P,T,r, E(P)|t,T,r, t(E)|P,T,r, t(P)|E,T,r, E(T)|P,e,r, t(r 0)|P,T,E. It is assumed that in every dependency other parameters is fixed, but can be changed with the help of special data window. Here E-electrical field intensity, P-outer pressure, T-temperature, r0-radius of the most “dangerous bubble” that is on electrode. The liquid for treatment can be chosen from a library. For a new dielectric liquid it is necessary to input its physical properties: dielectric permittivity ε E, vapor pressure P,(T), viscosity η(T), surface tension σ. With the help of dialog windows one can choose required dependency and its physical parameters
