harmonics) active, reactive (ADE7878, ADE7868, and_ADE7858), apparent energy measurement and equalization calculation, and basic active and reactive power measurement (ADE7878) and equalization calculation. A fixed-function digital signal processor (DSP) performs this signal processing. The DSP program is stored in the internal ROM memory. The ADE7854/ADE7858/ADE7868/ADE7878 are suitable for measuring active, reactive, and apparent energy in various three-phase structures such as wye or delta services, with both three and four conductors. The ADE78xx devices provide system calibration functions for each phase, namely rms offset correction, phase calibration, and gain calibration. The CF1, CF2 and CF3 logic outputs provide a wide selection of power information: total active, reactive and apparent power, or the sum of current rms values, as well as basic active and reactive power. The ADE7854/ADE7858/ADE7868/ADE7878 contain waveform sample registers that allow access to all ADC outputs. The device also includes power quality measurements such as short-duration low or high voltage detection, short-duration large current changes, line voltage cycle measurements, and angle between phase voltage and current. Two serial interfaces, SPI and I2C, can be used to communicate with the ADE78xx. A dedicated high-speed interface, the High-Speed Data Capture (HSDC) port.
