摘要： A metering unit, located in a distributed power network carrying a power-related waveform, comprises a sensor, a generator, and a memory. The sensor senses power-related parameters associated with the power-related waveform. In response to the sensor, the generator generates and transmits data representative of the power-related waveform. The memory is a sector-erasable flash EEPROM having stored therein programmable logic and main functionality firmware for execution by the generator. The logic is programmable by a user and executable by the generator to increase operations performed by the metering unit.

摘要： An improved metering unit is described which samples a power-related waveform and simultaneously captures its analog signal parameters for temperature and all phases of voltage and current, providing a more accurate and clearer waveform sample that effectively detects harmonics problems and does not require signal interpolation methods. The improved metering unit comprises signal conditioning circuitry interfacing with the power line for sensing temperature and all desired phases of voltage and current parameters of the waveform. The metering unit further comprises a processor having a timer output. The timer output controls track and hold circuitry and an A/D converter. The timer output places the track and hold circuitry in the hold mode to simultaneously capture temperature and all the desired phases of voltage and current of the waveform, and, at the same time, the timer output triggers the A/D converter to convert the captured analog signal parameters into digital sample values.
