The present invention relates to a system comprising a number of modules for monitoring and controlling an electrical installation as well as a method for this purpose. This may take place at a level down to one single output connected to one single electrical appliance. The monitoring and control comprise detection of accumulated and instant power consumption by means of a magnetic field sensitive detector. The accumulated power consumption may indicate undesirable stand-by power consumption or un~esir~~ e overconsumption of power. Instant power consumption may indicate electrical disturbances such as arcing faults. In a specific embodiment of the invention, a Hall sensor is used as a detector, and at least the detector and a relay are located in the immediate vicinity of a distribution board of the electrical installation. The power consumption is compared to reference values, and the electrical installation is controlled based on this comparison. Finally, it is described how the invention may be used to lit a power supplier control the electrical installation according to an established user profile. |
