Abstract: An electrical protection system includes a household electronic device and an electrical protection unit permanently interfaced therewith. The household electronic device is configured for detachable electric connection to an external household source and to utilize electrical power received from the household source. The electronic device operates according to an electrical power waveform, e.g., the device exhibits the electrical power waveform during operation. The electrical protection unit is configured to allow electrical power to pass from the household source to the electronic device if the power waveform is within a waveform profile, and to prevent electrical power from passing from the household source to the electronic device if the power waveform is outside a fault deviation of the waveform profile. The waveform profile is indicative of normal electrical operation of the electronic device, across its entire operational range.
