“…It was found in our studies of the behavior of oil shale under high voltages that PDs and electric degradation in oil shale of certain deposits occur at a significantly lower voltage [12] than in insulation materials [13,14]. For example, a voltage of 3−4 kV applied to an interelectrode gap of 10 cm induces significant PD activity in oil shale of the Huadan deposit (China) and leads to the formation of a low-resistance discharge channel between the electrodes.…”

The paper is devoted to the study of the characteristics of partial discharges in solid fossil fuels. The appearance of partial discharges in solid fuels occurs at very low voltages, which are not typical for most dielectrics. The activity of partial discharges leads to the onset of rock breakdown. The characteristics of partial discharges in the oil shale of the Huadan deposit (China), presented in the work, indicate the voltage value at which partial discharges arise and breakdown occurs, and also show how these characteristics depend on voltage. We attempted to explain the low value of the voltage of partial discharges in solid fuels, as well as to substantiate the possibility of using partial discharge characteristics to predict the breakdown of the interelectrode space for use in the technology of in-situ heating and the pyrolysis of solid fuels. Keywords: Oil shale, subterranean conversion, field distribution simulation, apparent chage measurement.

“…The heat source is an electrothermal breakdown channel. Heating starts from the moment when the electric discharge structures developing in the coal close the interelectrode gap [11]. At the time of the formation of the through conductive channel, its diameter is very small compared with the interelectrode distance.…”

In the nearest future, pyrolytic conversion of solid fossil fuels may become an important source of energy resources. Due to this fact, the technologies of heating of subterranean formations are created. This article describes the experience of creating the laboratory setup for the investigations of methods and modes for fuels heating in the conditions similar to the underground ones. Applied technical solutions and the results of their application are described.
