FIELD: electrical article manufacture.
SUBSTANCE: the invention is related to the quality control of the insulation of electrical articles during their manufacture, mainly when drying the articles with the hard insulation, based on the thermoreactive impregnating lacquers and compounds. The method essence consists in measuring the capacitance of the same insulation gap at two different frequencies. The frequency of 50-100 Hz is used a the low frequency, and the frequency of 10-100 kHz - as the high one. Then the humidity coefficient is determined as the ratio of the capacitance, measured at low frequency, the capacitance, measured (at high frequency. The humidity coefficient should be in the limits of 1.00-1.05.
EFFECT: increased accuracy and objectivity of the quality control.
