Voltage/Current Isolation TRIZ Cases
- Current Sensor Asymmetric Support for Wire Diameter Variations
An asymmetric support structure with an oblique surface stabilizes the wire center position, eliminating output fluctuations caused by varying wire diameters.
- Current Sensor Fault Detection Shared Signal Path
A current sensor merges fault detection into a shared signal path using digital processing components for efficient overcurrent monitoring.
- Planar Current Sensor with Segmented Dipole Coils for Channel Isolation
Segmented dipole coils in a planar current sensor reject uniform and gradient external magnetic fields while isolating signals from neighboring conductors.
- Contactless Power Measurement via Electric and Magnetic Field Detectors
A contactless measurement device uses electric and magnetic field detectors to capture voltage and current signals on AC power lines.
- Rogowski Coil with Dual Opposite-Wound Segments for Noise Cancellation
Opposite-wound coil segments and multiple sensors determine conductor position while cancelling external interference to enhance current measurement accuracy.
- Galvanic Insulation Voltage Measurement Using Transformer Tap
A measuring circuit samples secondary winding voltage during non-conducting intervals to isolate the signal from load effects.
