4.3.2 Phase Compensation
The CT, when used as a sensor, and the input circuit'spassive components together introduce an additional phase shift between the current and voltage signals that needs compensation. The SD24 converter has built-in hardware delay that can be applied to individual samples when grouped. This delay can be used to provide the phase compensation required. This value is obtained during calibration and loaded on to the respective PRELOAD register for each converter. Figure 9 shows the application of
PRELOAD.
