System and method for providing power to a power meter connected to a power line

摘要

The disclosure relates to a meter for monitoring usage of power provided by a power transmission system to a site. The meter comprises: a communication module to generate communications carried over the system; a request manager module to process messages received from a head end of the system; a meter module connected to a power feed of the system; a connection manager module to evaluate readings and data and to generate connection signals for the meter in view of the readings; and a relay having a first position where the power is connected to the site and a second position where the power is disconnected, the relay being controlled by the connection signals. The connection manager module generates a first signal for the relay to disconnect the power when an over-voltage condition or an over-current condition on the system has been detected.
