Certain issues of electrical purification of dielectric oils (for example, transformer oil) to remove micron- sized semiconducting and conducting particles of are considered. The solution of the problem about the dependence of parti- cle concentration on time at the output of electrofilter both at zero and non-zero flow rate is given. It is shown that in both cases a mathematical structure of the solution is the same, which makes it possible to use the same formulas with parameters of the given mode. Physical and mathematical interpretation of the experimental results is given. The equa- tions of theoretical dependences, corresponding to the experimental ones, are obtained and theirs graphs are plotted. The experimental data that are in good agreement with theoretical results are generalized by dimensionless logarithmic equations.
