The research results showed that between the parameters and wear intensity І there is a dependency:

(4) where А and В – constant coefficients. With decreasing value intensity of wear І increases, and upon reaching a critical level, the friction system switches from normal mechanical and chemical wear to the seizure mode (volumetric destruction), which is accompanied by a disproportionate increase in wear intensity (Fig. 8).

After connecting the device, its input is disconnected from the current collector. At the same time, the recording devices record the corresponding signal %. If a milliammeter is used as a recording device, then the adjustment resistor R12 must be used to bring the scale arrow to the maximum value that corresponds to
