In 1928, he, together with Vladimir Fock, created a theory of thermal disruptive discharge of dielectrics.
2.
Breakdown occurs quite abruptly ( typically in nanoseconds ), resulting in the formation of an electrically conductive path and a disruptive discharge through the material.
3.
Their construction usually feature a combination of a disruptive discharge coil with an interrupter to apply a high voltage, high frequency, and low current to the human body for therapeutic purposes.
