Vattvarmetr D5068 (D 5068, D -5068)

    Vattvarmetr D5068 is designed to measure active power in three-phase three-wire AC circuits at the uniform and non-uniform load phases as well as for the measurement of reactive power in three-phase three-wire circuits with a symmetric voltage and load phases with the unevenness of not more than 5%. Vattvarmetrov D5068 Class of accuracy:
 
    0.5 - in the modes of measurement of active and reactive power in the frequency range 45 - 65 Hz;
    1 - in the mode of measurement of active power in the frequency range of 65 to 1100 Hz.
Rated current: 1A. Rated voltage:   100V, 250V.
    Vattvarmetr D5068 are designed to measure active power in three-phase three-wire AC circuits at the uniform and non-uniform load phases as well as for the measurement of reactive power in three-phase three-wire circuits with a symmetric voltage and load phases with the unevenness of not more than 5%.
    Vattvarmetr D5068 is designed for use in moderate climate in enclosed dry heated rooms at the ambient temperature of 5 to 40 ° C and a relative humidity of 90% at a temperature of 25 ° C round;
    Vattvarmetr D5068 -04.1 designed for use in dry and humid tropical climate in a location with an enclosed air conditioned or partially air-conditioned at the ambient temperature from 1 to 45 ° C and a relative humidity of 80% at a temperature of 25 ° C.
 
    Technical data
 
    Accuracy class vattvarmetrov D5068 - according to GOST 8476-78:
    0.5 - in the modes of measurement of active and reactive power in the frequency range 45 - 65 Hz;
    1 - in the mode of measurement of active power in the frequency range of 65 to 1100 Hz.
 
    Basic vattvarmetrov D5068 are given in Table. 1. The nominal rate of active and reactive power 1. Current parallel circuit vattvarmetrov (7,5 ± 0,15) mA. Vattvarmetrov normal range of frequencies from 45 to 65 Hz, work - more than 65 to 1100 Hz.
    Maximum permissible error vattvarmetrov D5068 mode measurements of active and reactive power in the normal range of frequencies from 45 to 65 Hz is equal to ± 0,5% of the final value of the measuring range.
    Maximum permissible error vattvarmetrov D5068 measurement mode active power in the normal frequency range of 65 to 1100 Hz is equal to ± 1,0% of the final value of the measuring range.
    The limit of additional error vattvarmetrov D5068 caused by a deflection voltage of ± 20% of nominal value at a constant value of the measured power is equal to ± 0,5% of the final value of the measuring range.
    The limit of additional error vattvarmetrov D5068 caused by changes in ambient temperature from normal to any temperature within the operating range is ± 0,5% of the final value of the measuring range for each 10 ° C change in temperature. The normal temperature of -20 ° C if on the face of vattvarmetra otherwise stated value (tolerance ± 2 ° C).
 
    The power consumed in each series circuit vattvarmetrov D5068 corresponds to the values ​​given below:
in the normal range of frequencies from 45 to 65 Hz - 0.05 VA at rated current 1A and 0.12 V · A - at rated 5A;
in the normal frequency range of 65 to 1100 Hz - 0.6 VA at rated current of 1A and 0.7 VA - at rated current 5A. Response time vattvarmetrov D5068 does not exceed 4s. Overall dimensions (140 ± 1,25) x (195 ± 1,45) x (92 ± 2,7) mm. Weight does not exceed 2.0 kg.
