Device for evaluation of electro conductive properties of polymer materials includes connected in series bass band filter, square detector, smoothing resistor and input from automated switch to outputs of which with inputs two collection capacitors are connected, outputs of those are connected to common earthed bus, second automated switch, switch generator that is with output connected to control inputs of the both automated switches, differential amplifier and voltmeter. Additionally there are included two-winding vortex current indicator, resonance capacitor and generator of alternating voltage high-potential output of which is connected to input of the second automated switch. |
