1. A remotely readable apparatus for metering of a plurality of electricity consumer lines, comprising: a meter head enclosed with a first housing, said meter head comprising one or more metering points, wherein said meter head measures electricity usage for each of the plurality of electricity consumer lines; andone or more sensors that sense environmental conditions in a second housing enclosing a distribution transformer that steps down voltage from a distribution level to a consumer level, said one or more sensors in electrical communication with said meter head and wherein said sensors are not operable to sense environmental conditions in said first housing, and wherein said meter head is operable to connect and disconnect service on one or more of said plurality of electricity consumer lines in response to information received from said one or more sensors, without affecting voltage supplied to said distribution transformer;wherein a transponder is in communication with said meter head and transmits data received from said meter head to a remotely located computer, and transmits to said meter head data received from said remotely located computer,wherein said meter head transmits to said transponder data based on said data received from said one or more sensors,wherein said meter head is operable, based on data received from said transponder and responsive to said data based on said data received from said one or more sensors, to connect and disconnect service on said electricity consumer lines, andwherein said meter head is operable to connect and disconnect service on each one of said plurality of electricity consumer lines in a rotating disconnect/connect sequence, and intermittent power is provided on each of said electricity consumer lines. 2. An apparatus as in claim 1, wherein said one or more sensors comprise a temperature sensor that measures a temperature of said distribution transformer, and said meter head is in electrical communication with said temperature sensor. 3. An apparatus as in claim 1, wherein said one or more sensors comprise an oil-level sensor that measures level of oil in said distribution transformer, and said meter head is in electrical communication with said oil-level sensor. 4. An apparatus as in claim 1, wherein said meter head is operable, in response to an interruption in flow of electricity being received from a distribution transformer, to disconnect service on one or more of said electricity consumer lines. 5. An apparatus as in claim 4, wherein service is disconnected via actuation of corresponding relays, and power to actuate said corresponding relays is stored in and received from a battery back-up system. 6. An apparatus as in claim 4, wherein service is disconnected via actuation of corresponding relays, and power to actuate said corresponding relays is stored in and received from a capacitive storage system. 7. An apparatus as in claim 4, wherein said meter head is operable, in response to restoration of electricity being received from a distribution transformer, re-connect service on said electricity consumer lines. 8. An apparatus as in claim 4, wherein said meter head is operable to store data reflecting, for each relay, a state existing immediately prior to interruption of electricity flow, and wherein said meter head is operable to actuate corresponding relays to re-connect service on said electricity consumer lines so as to restore each of said relays to said state existing immediately prior to interruption of electricity flow. 9. An apparatus as in claim 4, wherein, in response to restoration of electricity being received from a distribution transformer, said meter head is operable to re-connect service on said electricity consumer lines, said re-connection being in a sequence selected to minimize a surge or excessive load on a substation network. 10. An apparatus as in claim 1, wherein said transponder is in communication with said meter head via power line communication. 11. A method of metering a plurality of electricity consumer lines, comprising: measuring, via a meter head in a first housing, electricity usage for each of the plurality of electricity consumer lines; andsensing environmental conditions in a second housing enclosing a distribution transformer that steps down voltage from a distribution level to a consumer level, via one or more sensors in electrical communication with said meter head and wherein said sensors are not operable to sense environmental conditions in said first housing, wherein said meter head is operable to connect and disconnect service on one or more of said plurality of electricity consumer lines in response to information received from said one or more sensors, without affecting voltage supplied to said distribution transformer, and wherein said meter head is operable to connect and disconnect service on each one of said plurality of electricity consumer lines in a rotating disconnect/connect sequence, and intermittent power is provided on each of said electricity consumer lines.
