Abstract: There is provided an intelligent electronic device for responding to user data and information requests regarding power usage and power quality for any metered point within a power distribution system. The intelligent electronic device includes a first network interface which receives client side information and data requests, which are processed in accordance with a network protocol and forwarded to a network interface via a network socket interface translator which translates management signals to facilitate the eventual data transfer.
