FIELD: measurement engineering.
SUBSTANCE: method can be used for measurement of temperature of isolation of electric machines' windings. Ac voltage is applied to any two points of circuit which points are electrically connected with winding and case of electric machine through blocking capacitor. Stray electric capacitance of case insulation of windings is measured in relation to case of machine. Value of isolation's temperature is judged from value of stray electric capacitance.
EFFECT: improved precision of measurement.
