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.
Claims19
An electrical safety device comprising:
- 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 provide a contactless measurement of a temperature of the electrical plug when received in the socket;
- a processor in communication with the thermal sensor, the processor configured to determine when the temperature exceeds a predetermined threshold;
- a wireless communications link operably coupled to the processor and configured to connect with one or more remote devices to form a wireless network, the wireless communications link further configured to send a signal, via the wireless network, to a remote device in response to the processor determining that the temperature of the electrical plug has exceeded the predetermined threshold;
- and one or more of:
- a smoke and/or gas sensor;
- a carbon monoxide sensor;
- and
- a current sensor;
- wherein the processor is configured to compare behavior of a combination of sensed parameters against response data stored in a memory to identify a presence of a hazard.
