摘要： Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. All recorded and computed data is moved to non-volatile storage via direct memory access transfer in the event that a power quality event jeopardizes the operating power of the meter. The meter provides a power supply utilizing high and low capacitive storage banks to supply sufficient energy to survive short duration power quality events which jeopardize the meter's operating power. The power supply also enables the meter to initiate and complete a shut-down routine allowing the storage of he recorded and computed data. Further, a separate power supply utilizing a capacitive storage bank is utilized to operate a communications device when the operating power is lost. The communications device switches from the meter power supply to the alternate capacitive storage bank when an power outage occurs and then initiates a connection with an external network to report the loss of operating power and send the appropriate power management data.
