Revenue grade meter with high-speed transient detection

A system for providing high-speed transient detection and power quality analysis in a revenue grade power meter, comprising:

• a power metering device for monitoring power metering parameters of power consumed by a user or provided by a provider for metering purposes at a first scanning rate;
• a plurality of digital 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, storing the detected high-speed quality events in time synchronization with the monitored power metering parameters if the high-speed quality events detected are above the predetermined threshold in a memory, and disregarding the detected high-speed quality events if the detected high-speed quality events are below the predetermined threshold;
• the memory stores the predetermined threshold, the monitored power metering parameters, the detected high-speed quality events, and a single waveform representation, to be displayed for the user;
• 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 the single waveform representation;
• and
• a display unit for displaying the contents of the memory.

A system for providing high-speed transient detection and power quality analysis in a revenue grade power meter, comprising:

• a power metering device for monitoring power metering parameters of power consumed by a user or provided by a provider for metering purposes at a first scanning rate;
• a plurality of analog high-speed peak detectors for detecting high-speed quality events of the power consumed by the user or provided by a provider at a second scanning rate, the second scanning rate being faster than the first scanning rate;
• an analog/digital converter for converting analog signals into digital signals to perform calculations and comparisons;
• a wave analysis component for comparing the detected high-speed quality events to a predetermined threshold, storing the detected high-speed quality events in time synchronization with the monitored power metering parameters if the high-speed quality events detected are above the predetermined threshold in a memory, and disregarding the detected high-speed quality events if the detected high-speed quality events are below the predetermined threshold;
