A device for estimation of insulation deprecation includes a nonlinear converter temperature-current, power supply source, controlled pulse generator, time counter, block for reveal of increased insulation wear, time counter, time of increased insulation wear counter, block for reveal of increased insulation wear and setting block. At that the converter current-voltage of phase C, converter current-voltage of phase B and converter current-voltage of phase A are additionally included to the device, those through the block for correction of voltage are connected to the converter temperature-current. |
