Electrical phase identification of a device (12) connected to a single phase of a multi-phase output of an upstream device (11), e.g. a two phase or three phase transformer, is performed by comparing a variation in voltage of the device over a reference time period with the variation in voltage at each of the phases of the multi-phase output over the same time period. The comparison may involve determining whether the respective variations are within a pre-defined threshold. The variations in voltage may correspond to an event within an electricity distribution network (10), such as an individual phase power outage, power restoration, dips, sag, swell, over- or under-voltage, or an injected control signal. The device whose phase is identified may be a utility meter that monitors a customers energy consumption. (Fig. 1)
