Abstract: A revenue grade power meter capable of detecting and recording high-speed power quality events, and method of operation. The power meter comprises a power metering device for monitoring power metering parameters of power consumed by a user or produced by a producer for metering purposes at a first scanning rate; a plurality of high-speed peak detectors for detecting high-speed quality events of the power consumed by the user or provided by the provider at a second scanning rate, the second scanning rate being faster than the first scanning rate; a wave analysis component for comparing the detected high-speed quality events to a predetermined threshold; and a multiplexor for combining the stored detected high-speed quality events in time synchronization with the monitored power metering parameters to display the power metering parameters and the detected high-speed quality events in a single waveform.
