Abstract
An electrical safety device is described which includes a socket arranged to receive an electrical plug of an electrical appliance to connect a current supply to the electrical appliance, a thermal sensor arranged to detect the surface temperature of an electrical plug when received in the socket and a processor in communication with the thermal sensor, the processor configured to determine when the sensed surface temperature exceeds a predetermined threshold. The invention also includes an electrical safety system comprising the electrical safety device configured to communicate with a remote device. The device and system provide early detection of electrical faults and hazards to reduce the risk of fires.

An electrical appliance comprising:
- a housing;
- internal electrical components within the housing configured to provide a function of the electrical appliance;
- a thermal sensor arranged to detect a surface temperature of the internal electrical components;
- a processor in communication with the thermal sensor, the processor configured to determine the presence of an electrical hazard when a detected surface temperature of the internal electrical components displays a particular behaviour;
- a wireless communication link configured to allow communication with one or more remote devices, wherein the electrical appliance is configured to send a signal to a remote device using the wireless communications link when the processor determines the presence of an electrical hazard;
- and
- a memory holding data relating to surface temperature behaviour associated with a particular hazard,
- wherein the processor is configured to receive surface temperature data from the thermal sensor and compare this against the data stored in the memory to determine the presence of a hazard.
An electrical appliance comprising:
- a housing;
- internal electrical components within the housing configured to provide a function of the electrical appliance;
- a thermal sensor arranged to detect a surface temperature of the internal electrical components;
- a processor in communication with the thermal sensor, the processor configured to determine the presence of an electrical hazard when a detected surface temperature of the internal electrical components displays a particular behaviour;
