摘要： Systems and methods for monitoring power in a conductor. A flex circuit may include multiple layers including a voltage sensing layer, a coil layer, and a ground layer. The coil layer includes traces that form a coil structure around a conductor when the flex circuit is wrapped around the conductor. The coil layer generates a voltage that may be integrated to determine a current in the conductor. When the flex circuit is wrapped around the conductor, the voltage sensing layer is closest to the conductor. The voltage sensing layer forms a capacitor with the conductor. Using an adjustable capacitive voltage divider, the voltage of the conductor may be determined from a voltage signal received from the voltage sensing layer.

摘要： Power quality detection, monitoring, reporting, recording and communication in a revenue accuracy electrical power meter is disclosed. Transient events are detected by monitoring the wave shape of the electrical power and comparing deviations to a known threshold. Sags and Swells are detected by computing root mean square value over a rolling window and comparing the computed value with a known threshold. Harmonic frequencies and symmetrical components are quantified by a known algorithm and compared with a known threshold. Incoming waveforms are stored to memory. 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. Further, 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.

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.
