Impedence Measurements TRIZ Cases
- Low-impact Power Grid Probing via Frequency Offset Filtering
Frequency offset filtering isolates low-amplitude probe responses from power grid noise, resolving measurement precision against grid disturbance constraints.
- Food Internal Property Analysis System
Central unit processes camera and electrode signals to determine food internal properties, replacing inaccurate visual inspection methods.
- Grid Impedance Estimation via Angular Error Minimization
Estimates grid impedance by minimizing a performance index against angular errors, resolving complexity in real-time adjustments.
- Voltage Divider Insulation Monitoring for Melting Furnaces
An ohmic-inductive voltage divider allows real-time ground fault detection in melting furnaces despite high leakage currents.
- Impedance Measurement Circuit with Chopper Calibration
A measurement circuit uses a chopper and switch matrix to isolate analog signals from DC offset errors during calibration phases.
