Page 30: Chapter 3 Operation: Base Metrology
K could be viewed as the Hall sensor intrinsic gain and is maximized by the appropriate choice of semiconductor materials that have been uniquely optimized by Itron for the CENTRON meter. For the metering application, the biasing current i applied to the sensor is generated from the line voltage (V) using a resistor (R). -
Page 31: Power Measurement Principle In 2S
Operation: Base Metrology The output voltage of the Hall Effect device is then: GPower hall ⁄ Where G G is the combined gain factor of the entire system (Voltage to biasing current, line Current to flux density, Hall sensor). Figure 3.1 Power Measurement Principle in 2S From the power information available at the output voltage of the sensor, the meter architecture is simplified over previous designs as the multiplication has already taken place (see Figure 3.2). -
Page 32: Centron 2S Cl320, 4S, 12/25S
This shift causes a small power factor error that is uniform across the dynamic range (load curve) of the meter. Itron compensates for this shift in the CENTRON by the use of a capacitor in the biasing current circuit. -
