Dynamo-Electric Motor Meters TRIZ Cases
- Bidirectional Energy Network Control for Heat and Power Balancing
Real-time control balances cogenerator, heat generator, and grid power to support bidirectional heat and electricity trading at lower cost.
- Electric Motor Test Rig Using Low-Voltage Fault Signatures
Low-voltage motor testing uses speed variance and voltage spikes to quickly flag brush, commutator, and bearing faults.
- Automatic Disconnect System for Utility Meter Safety
A detector monitors utility meter presence to automatically disconnect alternate power sources, preventing unintended energization during maintenance.
- Capacitive Isolation Barrier for Sigma Delta Modulator
A capacitive isolation barrier electrically isolates the digital output of a sigma delta modulator.
- Rogowski Coil Integration Using High-Pass Filter
High-pass filters cancel integrator poles to eliminate approximation errors in Rogowski coil systems.
- Meter Socket Insert for Local Generator Interconnection
A meter socket insert interfaces local generator inverters with existing power meters, bypassing panel expansion to simplify installation.
- Power Monitoring System Using Toroidal Current Sensors
Wire wound toroidal coils sense current at circuit breakers, reducing installation complexity while maintaining measurement precision.
- Electronic Device Power Outage Duration Tracking
An electronic device records AC connection times to calculate outage duration and display notifications.
- Automatic Calibration Circuit for Power Detector Accuracy
Calibration module stabilizes output voltage via trim current to maintain accuracy under temperature and process variations.
- Peak Load Covering Device with DC Accumulator and Inverter
A power inverter fed by a direct current accumulator supports consumer electricity supply through parallel connection.
- Front-Accessible Test Switch Terminals
