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： A power meter for measuring power parameters on one or more electrical power lines/loads is configured to include a revenue class metering module and a power quality metering module. The revenue class metering module and the power quality metering module may use the same measured voltage and current signals to generate revenue accurate power consumption information and power quality information, respectively. The power meter may also include a plurality of filters configured to attenuate high frequency signals included in the voltage and current signals. Each of the filters may be configured with a corner frequency, gain and signal propagation delay that is substantially equal. The filtered current and voltage signals may be received and processed by the revenue class metering module, and the power quality metering module to generate revenue accurate power consumption information and power quality information, respectively. Alternatively, the filtered current and voltage signals may be received and processed by the power quality metering module to generate power quality information, and unfiltered current and voltage signals may be received and processed by the revenue class metering module to generate revenue accurate power consumption information.
