Apparent power power meter DAQ

active powerreactive poweranalog

The system consists of a moving coil movement with installed transducer which measures the reactive power in a sinusoidal or not sinusoidal current circuit and which transformes it into an analogue signal. This is possed to the moving coil movement. These instruments have the same system and all technical explanations as our active power meter. The standardized scale final values are 1-1,2-1,5-2-2,5-3-4-5-6-8 and respectively the decimal multiples of those. Other values on request. Consumption The consumption per current path is < 0,2 VA The current consumption in the voltage path is < 3,9 VA Scales 90º scale, practically linear. Coarse-fine division- The full-scale value must be between 0.2 and 2 times rated apparent power, which is calculated as follows: • For single-phase AC: S(W) = Primary voltage (V) x Primary current (A) • For three-phase AC: S(W) = √3x Primary line-to-line voltage (V) x Primary current (A) Unless otherwise indicated, the full-scale value is calculated by rounding S down to one of the following standard value: 1 - 1,2 - 1, 5 - 2 - 2,5 3 - 4 - 5 - 6 - 7,5 - 8 or their decimal multiples.. On request: Zero center. Por example, -100-0-100kW Overload capacity according to DIN 43780 Overload capacity continuously 1,2 ln.
