Emergency Protective Circuit Arrangements TRIZ Cases

See how a segmented cryogenic container isolates the refrigerating machine from the magnet fiel

Multiple MEMS sensors track vibration, pressure, sound, and load shifts to detect trapped children and block appliance operation.

Input-voltage monitoring and electric recycle valve actuation help gas compressors avoid surge, trips, and mechanical stress during dips.

Sets the failsafe node to the higher of supply or pad voltage to keep the output transistor off and prevent leakage during supply drops.

Sequence mutual coupling parameters Z21 and Z20 improve fault location on untransposed transmission lines despite phase imbalance.

A reverse polarity protection circuit redirects current away from the body diode to limit heating and protect a high-side switch chip.

Excess current sensing forces a hard short in faulty VRD powerstages, triggering upstream protection before smoking, burning, or flames.

A PCB-mounted fuse cuts overcurrent in a battery module, while a detachable transparent cover enables fast replacement and status checks.

A relay and solid-state handoff keeps AC power continuous during source transfer, avoiding break-before-make interruption and costlier switch designs.

Fault voltage and extrapolated pre-fault current signals enable accurate line impedance and earth fault location in non-rigidly grounded networks.

Charge current measurement diagnoses current breaker failure during cutoff commands while keeping vehicle loads powered and avoiding extra switch circuits.

Traveling-wave reflections at two busbar sensors let IEDs locate conductor faults accurately without high-precision time synchronization.
