FIELD: instrument engineering; agricultural and industrial purposes.
SUBSTANCE: method can be used for improving truth of measuring of real consumption of electric energy. Electric heating of lower surface of Carbolite case of three-phase induction meter is turned on in separate metering distribution board depending on environment temperature due to contact heating of multiple-electrode composition electric heater. Temperature is regulated automatically depending on environment temperature.
EFFECT: reduced power intensity.
