Abstract
Aspects of the invention relate to an electric meter (100), a system (606), and a method (800). The electric meter (100) comprises a metering engine (116) to detect electrical energy consumption. The electric meter (100) comprises a detection system (104). The detection system (104) is configured to create a star point (127) from phases (L1, L2, L3) from a multi-phase power source (1). The detection system (104) is configured to measure a voltage between the star point and a neutral conductor or an earth conductor. The detection system (104) is configured to transmit an output signal in dependence on the voltage exceeding a threshold.
