An electrical supply measurement and management system includes a plurality of power sensors (5). Each sensor (5) is clamped to a power line (4) leading to a consumer's premises (2). Communications transmission units (7) are associated, and in communication, with groups of the sensors (5). The system includes a number of communications reception units (8) in communication with the transmission units (7) via the power supply network. One reception unit is located at the supplier's premises and a reception unit (8) is located at each consumer's premises. The reception units (8) facilitate management of electrical power consumption. Each power sensor (5) measures a magnetic field around the line (4) to determine the current in the line (4) and, in so doing, to calculate power use. |
