Power Measurement By Current/Voltage TRIZ Cases
- Filter Circuit Resistance Control for Load-Dependent Power Loss
A variable DC resistor is adjusted from load power and voltage to keep filter-circuit loss within a defined fraction and stabilize power delivery.
- Non-Contact Energy Meter Calibration for Accurate Voltage Sensing
Automatic feedback calibration corrects temperature- and position-driven voltage sensor drift for more reliable non-contact power metering.
- Electrical Rotating Machinery Cavitation Detection via Frequency Noise
Electrical signal frequency analysis detects cavitation in pumps and propellers, enabling speed adjustment to avoid gas locking and downtime.
