Engineering Contradiction Analysis
1Measurement precision
If Rogowski coils are used to monitor current signals, then current conditions can be calculated accurately, but the installation becomes challenging due to susceptibility to noise and signal distortion
Solution Approach 1:
A mobile device serves as an intermediary between the Rogowski coils and the configuration system. The mobile device provides a user interface for phase alignment configuration and receives calibration data, simplifying the installation process by mediating between the physical coils and the configuration requirements without compromising measurement precision
Solution Approach 2:
The system changes operational parameters through calibration data stored in the mobile device. By adjusting phase alignment parameters and calibration factors through the mobile interface, the system adapts to specific installation conditions, making installation easier while maintaining accurate current measurements
2Ease of operation
If Rogowski coils are installed without proper phase alignment configuration, then installation is simpler, but measurement accuracy deteriorates due to improper phase alignments
Solution Approach 1:
Phase alignment configuration is performed preliminarily through the mobile device interface before actual current measurements begin. The system stores calibration data and phase alignment settings in advance, so that when measurements are taken, the coils are pre-configured for accurate operation without requiring complex on-site adjustments
Solution Approach 2:
The system implements feedback through the mobile device, which receives calibration data from the Rogowski coils and provides guidance for proper phase alignment. This feedback loop allows installers to achieve accurate measurements by following mobile device instructions, maintaining installation simplicity while ensuring measurement precision
3Reliability
If shielded cables and twisted pair wires are used to reduce noise interference, then signal integrity improves, but device complexity increases
Solution Approach 1:
The system replaces complex physical shielding and wiring arrangements with electronic signal processing and digital calibration methods. The mobile device processes signals and applies calibration algorithms that compensate for noise and interference, achieving high signal integrity without requiring complex physical modifications to the Rogowski coil system
