<p>Instantaneous current and voltage values are digitized at each of a plurality of electrical utility customer sites (18) and integrated by a processor to calculate electrical power consumed at each customer site (18). A communication interface couples the processor at each customer site (18) to a central processor (12) in a central utility site to communicate the power consumed values of each customer site (18) to the central utility site (10). In a preferred emdodiment, the automatic meter reader apparatus is mounted in an electrical watthour meter socket adapter (40) which plugs into a watthour meter socket (30) at each customer site (18). Telephone modem circuitry mounted in the socket adapter connects to telephone lines to communicate calculated power values from each customer site (18) to the central utility site (10).</p> |
