Abstract: FIELD: electric measuring technique. 
     SUBSTANCE: method can be used for automatic correction of angle error of current transformers, particularly, electric energy electron meters. Method is based upon measurement of instant values of input current and voltage signals as well as angles φ among them. Correction of angle error of tested current transformer is performed on base of measurements. Electric energy meter is graduated, which meter has current transformer to be tested, by means of connecting meter to assembly for graduation of meters at power coefficient being equal to cos(φ)=1. Then power coefficient being equal to cos(φ)=0,5L is preset in assembly for graduation of meters, and relative error δ1 of meter is measured. Then power coefficient being equal to cos(φ)=0,5C is preset at assembly for graduation of meters and relative error δ2 is measured. After that the relative error of meter, which error was induced by angle error δ of current transformer, is calculated. On base of measured value of relative error δ of meter the value of sine of angle error sin(Δφ) of current transformer is calculated. Correction coefficient is calculated on base of calculated value of sin(Δφ). Precision of measurement of meters is improved due to simplified calculations of angle error of current transformer and due to introduction of automatic correction of angle error of current transformer. 
     EFFECT: improved precision of measurement.

Granted: 2008-09-10
Abstract: FIELD: metrology. 
     SUBSTANCE: invention relates to updating the vibration element pickoff and can be used for measuring forces, pressure, acceleration etc. The proposed method consists in incorporating an extra negative temperature factor heat-dependent capacitance with the vibration pickoff design, since the known pickoff features a resistance positive temperature factor. Heat-dependent resistance R α  compensates a multiplicative temperature error while heat-dependent capacitance C β  compensates an additive temperature error. The vibration element oscillations maintenance circuit pre-tuning is affected at a maximum operating temperature. The oscillator starting frequency and the oscillator frequency departure from the rated magnitude of the measured parameter is recorded. Temperature factors of resistance α α  and capacitance α β  of heat-dependent resistance R α  and capacitance C β  are calculated, respectively. By solving the set of equations, the required heat-dependent resistance R α  and capacitance C β,  heat-independent resistance R "2Н"  and capacitance C "1ГН" .are calculated. By using an electro-erosion or laser adjustment, the rated values of calculated heat-dependent resistance R α  and capacitance C β  are reduced to designed values. 
     EFFECT: higher accuracy of minimising vibration element pickoff temperature error at constant temperatures.
