FIELD: electricity.
SUBSTANCE: invention relates to the sphere of electrical engineering and can be used in electric machines. Contactless current measurement is implemented in device and method for current measurement in bearing. Contactless voltage measurement is implemented by means of in-series circuit of capacitors. Thus voltage of bearing is peculiarly good for measurement in the range of high frequencies.
EFFECT: improved estimation of bearing currents.
