Basic activity directions   Development of concepts for the protection of electrical engineering equipment against the overvoltage in order to ensure sustainable exploitation of power systems.

Development theoretical foundations of electrophysical methods used in technological processes.

Investigation of electrical properties of composite materials based on polymer dielectrics.

Main scientific achievements  An analytical algorithm for constructing a model reflecting the high frequency overvoltage and other real processes taking place during switching in complex electrical networks was developed. The model construction allowed the precisely definition of requirements applied to protective devices of electric networks including the non -linear overvoltages limiters. Based on received results the varistors receiving technology was developed and nonlinear varistors of different designations was made and tested. With the use of ferromagnetic cover the technology of making frequency independent nonlinear varistor was elaborated.

Taking into account electric and magnetic properties of micro-dimensional powders of ferromagnetic material NiZn, based on percolation theory, the theoretical model is mad e, the resistive element with effectively suppressing high-frequency noise and overvoltages in the low-frequency electric networks was designed and manufactured. In the resistor the structure of electric and magnetic fields are defined. Resistive element is demonstrated on the exhibition of technical achievements in Moscow.

By the complex calculations of wave processes to take account of the resistive current limiters based on high superconducting a mathematical model allowed to carry out theoretical computer simulation was designed with purpose of taking into account resistive current limiters based on high temperature overconductivity.

To protect against ferroresonance and high-frequency overvoltages for numerical experiments and computer modeling the algorithm was proposed. It is determined that protection against ferroresonance and high-frequency overvoltages can be accomplished by a single set.
