Electrical Measurements TRIZ Cases

A sealable electricity meter features a front optical communication interface and receptacle for remote data reading access.

A detection system adjusts signal phase to optimize power usage and accuracy.

A loop antenna coupled to a marginal oscillator detects buried objects by monitoring resonant circuit quality factor changes.

Removable conductive bars resolve terminal space constraints by supporting both through-cable and non-through-cable connections without changing the meter.

Eliminating correlated polynomial coefficients reduces calibration time while correcting nonlinear measurement deviations at unsupported points.

A measurement domain error analysis method calculates load differences during single load jumps to determine sub-meter deviation.

An impedance learning algorithm calculates individual phase impedances using voltage and current correlation terms within an electricity meter.

Continuous signal comparison prevents baseline drift from external objects, ensuring precise touch location detection.

A display unit presents actual and comparative power consumption data in identical fields on a single screen for injection molding machines.

Reference current heats the measuring resistor directly, eliminating bulky temperature chambers and reducing calibration time.

A diagnostic sensor generates a reference voltage by periodically switching current direction to validate Hall-effect integrity.
